Jig for drilling holes: how to use and how to make it yourself? Jig for drilling holes: tips for choosing, prices Furniture jig for dowel.

Today, construction uses devices that facilitate the processing of materials. For example, a jig for drilling holes is one of those devices that allows you to carry out work without the use of any marking tools.

What is the product?

The presented device allows you to do the job as accurately as possible. It is a special box that provides the necessary hole parameters. That is, you can easily adjust the angle of entry of the drill into the material being processed. Moreover, if there are several parts, then drilled holes will match.

It must be said that such devices can be purchased at any hardware store. Their cost ranges from 1000-2500 rubles. However, you can make a jig for drilling holes yourself. This is especially necessary if the work requires special parameters.

Advantages of the device

The drilling jig has the following advantages:

Reasonable cost and the possibility of making it yourself.

There is no need to use a ruler, pencil or other means to mark the surface to be treated.

Reducing the labor intensity of the procedure.

Very simple use of the product, intuitive even for an amateur.

As you can see, a hole drilling jig is a very useful device for household or for a small business.

Areas of application of the product

In principle, such a device can be used almost anywhere. For example, it can most often be found in the process of making furniture. This kind of work requires precise parameters. Using measuring instruments takes a lot of time. This entails additional expenses, which can be disastrous for a small business.

The conductor is also a very important device in mechanical engineering. Here the equipment of the device plays a huge role. It must be as accurate as possible. As you can see, the presented device is quite common and useful. It makes your work much easier.

Device design

The jig for drilling holes, a drawing of which you can see in the article, may have different designs. It all depends on the purpose for which the device will be used. For example, if you purchased a device in the form of a small strip or corner with holes drilled in one line, then with its help you can make holes in one row at right angles.

If you do not need such a design, but need more difficult option with holes that are not on the same axis, then you will have to make the device yourself. You can find out how to do this below. However, first you need to understand the varieties of products presented. As you can see, the jig for perpendicular drilling of holes has a not too complex structure that even an inexperienced craftsman can figure out.

Classification of devices

So, we can distinguish the following types of devices:

Stationary. They differ in that they do not have rotating elements capable of moving the workpiece. That is, those products that are drilled are of the same type.

Invoices. Their feature is considered to be simplicity of design and low cost. To operate such a device you simply need to put it on the part that will be processed. It must be secured with a washer and nut.

Tiltable. They are capable of drilling several holes in one part. Moreover, they can have different angles relative to each other.

Rotary. In this case, the location of the conductor bushing is determined by the dividing disk.

Rocky. Such products are most often installed on professional drilling machines. They are especially in demand in the mechanical engineering industry.

How to choose the right device?

In order for the hole drilling jig, the photo of which is presented in this article, to successfully cope with the tasks assigned to it, you need to purchase correct device. When choosing and purchasing, try to follow these recommendations:

1. Type and purpose of the device. This parameter is the most important. If you choose the wrong device or its accessories, it will be useless to you and your money will be wasted.

2. Cost of the device. This parameter is also important. You should not give preference to the cheapest products that may come apart the first time you use them. Buy durable metal devices.

3. Manufacturer's warranty. Do not purchase an item from basement. There you are not insured against counterfeits or defective goods. It is better to contact an official certified point of sale, where you can exchange the product under warranty if it does not suit you or turns out to be non-functional.

4. Additional features. Today, a jig for drilling pocket holes can be equipped with special devices, which help eliminate dust during operation, or other devices.

5. Manufacturer. Here everything depends on your taste and the reputation of the manufacturer. Now the most popular is the Wolfcraft hole drilling jig.

Features of self-production

This is not at all difficult to do. First you need to select required material. A channel or corner is best suited for this purpose. Naturally, before processing the workpiece, it is necessary to make a template according to which the holes will be drilled. The diagram can be drawn on a regular sheet of paper.

Next, you need to make markings on the workpiece itself. After this, it must be clamped in a vice or with clamps, and only then drilling can begin. Please note that doing this strictly perpendicularly is quite difficult. The fact is that you can manually make a hole with a certain deviation. Moreover, the thicker the workpiece you choose, the more difficult it will be to work with.

Next you just need to drill holes at the marked locations. When doing this, take into account the diameter of the drill. It must exactly match the size of future holes on the material being processed. It is best to use a drilling machine for this purpose. It is this that will allow you to achieve the desired angle of 90 degrees. If drilling machine no, then the drill must be fixed so that it does not deviate. To do this, you can use all kinds of stands.

Features of the device

The KWB hole drilling jig, like any other device of the presented type, must be used correctly. Only in this case will you be able to achieve a positive result. So, try to comply with these conditions:

During operation, all parts, as well as the device itself, must be as clean as possible from dust or other contaminants.

Try to choose exactly the drill that will suit you in diameter.

Please note that when installing the jig, it must lie flat against the plane of the table. Naturally, at this stage you should also set the drilling depth.

When selecting the rotation speed of the drill, it is necessary to check that the drill is installed correctly for runout.

The workpiece must be very firmly fixed to the jig.

The drill must be brought to the product through the guide sleeve and drilling must begin.

Please note that you should not press too hard on the tool while working. Otherwise, the drill may simply break or lose its sharpness.

After completing the work, you must carefully remove the tool from the part and unscrew the jig.

During all manipulations, try to comply with safety rules as much as possible. For example, wear protective clothing, gloves and goggles. If you feel that the tool is starting to malfunction, stop working immediately. Otherwise, you risk injury.

That's all the features of using the conductor. Good luck!

When furniture is created, almost all parts have to be joined end-to-end. This is done using dowels in which holes are made. This is where a special part is needed. You can buy it or make a furniture jig with your own hands.

What is a furniture conductor?

A jig is a strip that has several holes and sleeves. It is applied to the desired part, the drill is inserted into the sleeve and a hole is made. To secure two parts you will need the help of one conductor, and the parts are fixed as securely as possible.

• precision drilling;
• simple and quick creation holes.

At the same time, conductors are used not only during construction, but also in mechanical engineering. Also this device allows you to drill cylindrical workpieces and pipes.

Different types of conductors

Depending on the industry, conductors are divided as follows:

• Invoices. They got their name because of their area of ​​application. This device is applied to the workpiece and fixed, with the help of which holes are made.
• Rotary. They are used to drill cylindrical holes. In this case, the rotary axes can be located horizontally, vertically, or at an angle. The body here is equipped with rotary bushings.
• Tiltable. They are used when holes are created in several planes.
• Sliding. Used to make each individual hole. In this case this model It is not fixed to the surface, which means it is not the most convenient.

DIY furniture conductor

As we already wrote above, this product is needed when assembling furniture. Some people prefer to buy it, while others prefer to make a furniture jig for drilling holes with their own hands. Such products are sold in any construction stores; here it is important to select finished products for specific goal. The cost of a furniture jig will depend on its size, purpose and manufacturer.

The simplest option is inexpensive, but professional equipment with various additional functions costs quite a lot. Therefore, today they are increasingly making furniture jigs and templates with their own hands.

They are made using a metal sheet or wooden board. Holes are made in them that will serve as guides. This work is not difficult, anyone can cope with it.

How to create a conductor

So, it’s not difficult to create a furniture jig with your own hands. To get started you will need:

• welding machine;
• Bulgarian;
• drill and some plumbing tools;
• You also need to prepare 10 x 10 mm reinforcement in advance.

First the workpiece is cleaned sandpaper and marking is performed. The distance from center to center is approximately 32 mm. Next, each template hole is drilled. After this, a stop is created - for this you can take a metal plate 1 mm thick. It needs to be bent and a place for carving is prepared. The last stage is the connection of these parts.

The product must be made as accurately and carefully as possible, otherwise it will be of no use, and in an unfavorable situation it can even damage the furniture. You can learn more about how to make a conductor by watching various video tutorials. The easiest way to make it is using a furniture template, which can also be obtained from specialists.

To ensure that drilling does not cause complications, a conductor is needed. This device will really be needed when assembling furniture. Of course, today you can buy everything, but it is better to make a furniture jig with your own hands, because then such equipment will definitely be suitable for each specific purpose.

We make our own jig for drilling holes

Description and features of the device

The jig is a strip with several holes and sleeves. Such a device is fixed to the required part, and then a drill is carefully inserted into the sleeve and a hole is made. To secure two parts you will need one jig, making the fixation reliable.

• drilling accuracy;
• simplicity and speed of creating holes.

It is worth noting that conductors are sometimes used in mechanical engineering, and not just in construction. Moreover, using this device you can make holes in cylindrical workpieces and pipes. The jig also allows you to make perpendicular holes.

Main types of equipment

All conductors used in various industries, are divided into several groups .

Methods and areas of application of the conductor

There are many ways to use this type of equipment. Naturally, the main area is considered building sector .

Furniture industry

When assembling furniture, you may find that some holes are missing. It is for this reason that you will have to drill various parts with your own hands. To ensure that the work does not cause difficulties, it is necessary to use a conductor. This will make furniture assembly accurate and quick. The use of such equipment is really important if you do not have a drilling machine.

Although today there is large selection of accessories and fasteners, dowels are still often used in the furniture assembly process. They must be installed very precisely, otherwise the parts will be displaced. To avoid this unpleasant consequences, you should use a conductor.

Drilling pipes

If it is necessary to prepare holes in pipes and various cylindrical workpieces, the use of a drill will not be best idea, since it often slips off, which means the holes will not have the desired shape. To make the job easier, you should use a universal jig.

It is worth noting that there is special equipment that allows you to perform perpendicular holes. and this is very important when processing rounded elements and edges of workpieces.

Purchased or homemade conductor?

As mentioned earlier, such a product is indispensable in the process of assembling furniture. Some people make these devices with their own hands, while others prefer to buy them.

Conductors are sold in almost any hardware store, however finished products may not be suitable for specific purposes. It is also important to remember that the cost of the device depends on the purpose, size and manufacturer. The most simple options are inexpensive. what can't be said about professional equipment with many additional features.

Many consumers prefer to make the conductor with their own hands. For this purpose you will need a metal sheet or wooden plank. Here, holes are prepared that will act as guides. In general, anyone can handle this kind of work.

Making a conductor with your own hands

As already mentioned, you can make a similar product for drilling yourself. To do this, you need to prepare a welding machine, an angle grinder, a drill and several plumbing tools. You will also need fittings dimensions 10x10 mm .

• The workpiece is cleaned with sandpaper and markings are made. According to accepted standards, the distance between centers should be about 32 mm.
• Next, template holes are drilled.
• Next stage- creation of emphasis. This can be a metal plate 1 mm thick. It is carefully bent and the place for carving is prepared.
• Then both parts are carefully connected.

To ensure that the process of drilling holes does not cause any difficulties, it is worth using a jig. Such equipment is really indispensable in the furniture assembly process. You can buy it, but it’s better to do it yourself, because a homemade device will definitely suit your specific needs.

A furniture jig for drilling holes, a drawing of a kind of template that allows you to accurately install assembly elements and greatly simplifies and speeds up the process.

Using this device you can make holes for:

Dowels
futorka
pinch bolt
mounting holes for mounting plate furniture hinge
mounting holes for furniture hinge cup
center for furniture hinge flange
center of the eccentric coupler

The design consists of two parts:

Marking unit
retainer

It is an “L” shaped plate made of thick sheet corrosion-resistant steel GOST 7350-77. in which through holes with a diameter of 8 and 3 (mm) are drilled horizontally and vertically. To ensure that the processing tool fits better into the holes, chamfers measuring 0.25x45˚ are made on its edges. The plate is hardened and ground.

Made from steel circle GOST 2590-88. which allows you to install a furniture jig for drilling holes at the required distance from the edge of the chipboard being processed. The movement step is ten millimeters.

How it works? For a better understanding, let’s open the article: “How to assemble cabinet furniture” and take a look.

Let's say we want to install a furniture hinge:

1. We lay the template on the facade.
2.
3. We drill a hole with a diameter of three millimeters to the required depth for the fastening screws of the cup.
4. We drill a hole with a diameter of three millimeters to the required depth for further processing. The prepared hole will be the guiding center for milling a hole for the flange of a furniture hinge with a diameter of thirty-five millimeters.
5. Place the template on the body.
6. We drill a hole with a diameter of three millimeters to the required depth for the mounting screws of the strike plate.

Let's say we want to install an eccentric coupler:

1. We lay the template on the horizontal surface of the chipboard part.
2. Install the clamp into the hole.
3. We drill a hole with a diameter of three millimeters to the required depth for further processing. The prepared hole will be the guiding center for milling the hole for the eccentric furniture screed with a diameter of fifteen five millimeters.
4. WITH chipboard end, one by one center line, drill through hole eight millimeters in diameter to the required depth

To better remember the sequence of operations, mill the hole numbers on the furniture jig to a depth of 0.25 (mm).

Jig for drilling holes: how to use and how to make it yourself?

When working with a hand drill, it can sometimes be difficult to maintain the specified direction of the hole. Conductors are also used if it is necessary to make a series of similar holes according to a template. For example, during carpentry work. In this case, the master does not waste time marking the tree, and is guaranteed to get the same result.

The jig is indispensable when drilling holes in pipes. But the main application is to pass holes at a given angle.

Let's consider various options for this useful device:

Jig for perpendicular drilling of holes

A simple furniture jig for drilling holes when assembling metal furniture. Details in the video material

Purpose - to obtain passes in thick workpieces, strictly at an angle of 90°. It is a set of bushings in a single body, or a bracket with replaceable working attachments.

By installing the device above the drilling point, you can start working without pre-punching. The drill accurately hits the center of the sleeve and does not deviate from the axis.

Important! The only problem is that the tool must be held on the workpiece, especially at the beginning of work. Otherwise, vibration may cause it to shift.

You can make such a drilling jig with your own hands. Thick textolite or solid wood is used. Perfect option— the use of extruder bushings for drawing wire. Worn bushings can be found at the factory.

The extruder nozzles are made of alloy steel, with the addition of pobedite. The service life is practically inexhaustible.

Conductor for cylindrical blanks or pipes

Making a hole in a sloping surface is almost impossible. It is especially difficult to start the process - the tip of the drill jumps off given point. The device will fix the direction and allow you to perform the work with high accuracy.

By adjusting the length of the fixing bolts, you can drill a hole tangentially to the center. If you don’t have such a tool at hand, you can make it from scrap materials. For example, from a block solid wood and strips of plywood.

To prevent the guides from being broken so quickly by the sharp edges of the drill, they can be reinforced with sleeves made of tubes of different diameters.

Furniture jigs for drilling holes deserve a separate description.

Jig for angled holes

This type of drilling is not very common, however, there are ways to fasten products to each other when this technology cannot be done without.

In fact, the hole is made tangentially, which is almost impossible to do while holding the drill with your hands.

Important! IN metal parts Such recesses can only be made using a milling cutter.

And for wooden blanks exists ready set.

Any carpenter is familiar with this method of drilling; professionals use this device all the time. Working with the jig is easy: you set the drilling height, the workpiece is pressed tightly against the stop, and you get precise oblique holes.

A stop-limiter must be put on the drill, otherwise the hole will end up through. Then the screw head will fall through. In addition, it is better to do such fasteners using a special drill with a double diameter.

It is difficult to make such a device yourself. Although there are simple options that are not particularly accurate.

There is a separate type of device: for drilling at an angle with an adjustable tilt. This is a specific jig that is not suitable for all workpieces.

The type of fastener indicated above is only suitable for an array. Pressed slabs cannot be joined this way.

Therefore, such a jig is not suitable for drilling holes in chipboard. To assemble trunnions and other furniture components made of hardboard, dowel fasteners are used.

Dowel hole jig

The device is designed to maintain the alignment of the holes. Otherwise you will not be able to install the spikes. By applying the jig to both parts to be joined, you will ensure a perfect connection.

If you decide to make such a conductor with your own hands, there is no need to look for drawings. We present two options for perfectly working homemade products:

Invoice template

It's very easy to make. A small piece of plywood and a sheet of hardboard are enough. With this device you can always drill a couple of coaxial holes for dowels.

Hardboard (or other transparent plastic) must be marked and calibration holes drilled. With their help, it will be easier for you to install the template in the right place. Thin-walled brass tubes must be driven into the holes. Otherwise, the wood drill will quickly destroy the guides.

Important! This device is only suitable for workpieces of a fixed width.

Then the spikes will be located in the center of the end. For wood of other sizes, it is necessary to make separate guides, or a universal jig template.

Self-centering jig

If you do not make furniture using standard panels, you need a universal tool. You can also make it yourself, and the materials are literally lying under your feet.

To make such a jig for drilling holes you will need a drawing and basic knowledge of geometry. Materials used: a piece of plywood 15-18 mm, a thin-walled tube suitable for a drill, several dowels, and a metal strip for the arms of the parallelepiped.

We make three identical parts: in the middle there is a hole reinforced with a tube, on the bottom side there are symmetrically located dowel legs. It is important that all three components are absolutely identical.

From metal we cut three identical arms with symmetrically located holes. They determine the linearity of the holes of the conductor.

We cut out grooves in three blanks and connect them using metal shoulders. The device works no worse than the factory one, at virtually zero cost.

Another way to connect furniture is to use the so-called confirmat. A separate tool is needed for this.

Making a self-centering conductor - video

Conductor for confirmation - types and possibility of production

Of course, such a device is on sale, and it is quite convenient and versatile. It is used to perforate the first part of the workpiece.

The second part of the workpiece must have two rows perpendicular holes. A different design has been developed for this purpose.

Of course, home craftsmen do not look for easy ways, and make a furniture jig jig for drilling holes with their own hands. Moreover, it does not have to be universal; you can adapt it to specific type joint of furniture panels.

Important! Any universal device is designed to save money.

Make a mistake in drilling when large quantities extra holes - as easy as shelling pears. Therefore, when self-production templates, make them narrowly profiled.

Don't be confused by the holes being the same size. Confirmat, as a rule, is issued according to certain standards. Therefore, the drilling diameter is the same.

We have discussed how to make a jig for drilling holes for fasteners. During assembly wooden structures and installation of doors/windows, hinged joints are used. Their fastenings must also be standardized and synchronous with each other. To avoid mistakes with the markings, a jig is used for the holes for the hinges.

It is almost impossible to install a standard furniture hinge without this template.

Any devices that can be used to standardize markings or drill holes improve the quality of work by an order of magnitude. In addition, purchasing (manufacturing) conductors allows you to save a lot of time during carpentry work.

Step 25 - furniture jigs

First, let's figure out what a furniture jig is? Every time, assembling some furniture, the master performs many completely identical marking operations (for example, marking 20 minifixes when assembling a cabinet means marking three completely identical holes with the same indentations). So, a jig is a device that allows you to optimize the processes of marking and/or drilling.

There are two main types of conductors: markinge And drilling. If the former serve to simplify marking, then the latter allow you to completely remove this stage from the work, starting immediately with drilling holes. Looking ahead, I will say that it is better to have both types.

Naturally, good conductors cost money, so people get rid of themselves and come up with their own homemade options, which are often no worse than factory ones.

Let's look at a few examples.

Marking furniture conductors:

Homemade conductor from a ruler. Probably the simplest and at the same time quite convenient and multi-purpose marking jig, which I recommend making. It is a ruler with a cross member screwed to it STRICTLY PERPENDICULAR. The ruler has holes drilled at certain distances from the beginning (for example, 32 mm for minifix, 100, 200, 300 mm for shelf holders, etc.)

Alternatively, you can use a ready-made carpenter’s square as a basis for such a jig (this is exactly what I have). It has its advantages (greater functionality) and disadvantages (less stable on the workpiece).

In addition, there are highly specialized conductors, for example, for marking holes for furniture handles .

For marking furniture hinges - This is a factory conductor, but who's stopping you from making one like that?

In general, using several pieces of plastic, metal and even plywood, you can make a simple marking jig to suit your needs.

Professional marking conductor Assistent - serious multi-purpose device. (I haven’t worked with it myself, but it seems to me that you can drill through it - it all depends on the bushings used).

Drilling jigs are more complex devices. The hole in them must not only be clearly opposite the desired location, but also be strictly perpendicular so that the drill does not go to the side during operation (for this, for example, replaceable bushings of different diameters are used or the thickness of the jig must be at least 10 mm).

Dubel-profi conductor from KVB - An excellent household drilling jig (for amateurs), for which a bunch of accessories are available (rulers, clamps, etc.) is inexpensive and simplifies the work. I have two.

Professional drilling jigs. I think that the principle of operation is quite clear from the photo. Replaceable bushings - for drills of different diameters

Another option - Condor conductor. It has a system for positioning the jig on the workpiece and replaceable bushings.

Again, to suit your needs, you can make conductors of similar functionality with your own hands.

In short, the topic of conductors is almost endless))). To each his own and for his own. The main points, as I think, I have depicted - then it’s up to your pocket and/or ingenuity.

By the way, you can order a Condor conductor in Chelyabinsk (or by shipment within the Russian Federation) from me at

A furniture jig is a simple mechanical device that serves to speed up and simplify the actions when drilling holes. The use of this device allows you to create technological holes without pre-applied markings and do this with perfect accuracy, as well as a adjusted slope. The device is indispensable during the assembly of furniture structures and carpentry work. For use in everyday life and in small-scale production, it is very easy to make a furniture jig with your own hands.

In essence, a furniture jig is an ordinary template with holes required diameter. The working part of the device is a rectangular block of solid material with holes located according to the required markings. For convenience, it can be equipped with adjusting and locking mechanisms. Based on the simplicity of the design, you can quickly make stencils for furniture with your own hands using available materials.

The jig ensures the desired direction of the drill at an angle of 90 degrees to the surface, eliminating the possibility of deviation. This is especially important when working with narrow parts of furniture, such as the ends of walls or doors. Without this device, it is quite difficult to maintain the required angle, which can lead to defects, because even a slight deviation in the direction of the mounting hole can make it impossible to assemble individual elements into a single structure.

For the perfect fit of furniture elements to each other, the accuracy of the location of the holes for fasteners is also of great importance. Those who make furniture with their own hands are often faced with the need to create a number of identical holes at a certain distance from each other. To make the work easier, make it faster, it’s easier not to mark up every time, but to use a template.

With the help of a conductor you can work with different furniture materials: wood, chipboard, MDF.

Selecting a model for production

Conductors of industrial production can be highly specialized and universal. Templates of the first type are used to perform certain operations on typical parts. Universal devices suitable for working with different materials and objects of various configurations.

By design features and functionality, conductors are divided into the following types:

• overhead - when used, they are applied to the surface in the desired area, fixed with clamps or held by hand. Used for drilling holes in flat parts;
• rotary - working part moves in both vertical and horizontal planes. Used when working with complex elements geometric shape and to create holes, the axis of which should be located at an angle;
• tipping - used to create holes in perpendicular planes.

A marking jig is used to mark the locations for drilling holes. It is much thinner and lighter.

The conductor device can be specially created for a certain type of fastener: dowels, confirmations, screws, corners. There are devices to simplify the process of installing fittings.

According to the type of fixation, furniture jigs can be sliding or fixed. The former can be moved freely over the surface if necessary, while the latter are rigidly fixed in the right place. The presence of an adjustment mechanism will help to combine the device with different types of workpieces.

For large manufacturers furniture, the presence of a variety of additional devices plays a decisive role, as they significantly reduce time costs. In this case, the cost of the tools does not matter much. A completely different approach to purchasing the necessary equipment from those who have a small furniture manufacturing plant or from independent masters manufacturing certain types of furniture. In this case, making furniture templates with your own hands turns out to be much cheaper and more practical. Choice the necessary options, the complexity of the device is determined not only by production needs, but also by the skill and experience of furniture manufacturers.

Materials and tools

To manufacture a device, you must first decide on the tasks that it will perform. Accordingly, the necessary material is selected from which the furniture template will be made with your own hands. The most durable, reliable and “long-lasting” is considered to be a metal conductor. To create a furniture jig for drilling with your own hands, it is permissible to use wood, plywood, textolite, and plexiglass. This is due to lower labor costs and cheaper materials. All this is important, especially if you are going to make several different templates yourself.

To make a conductor, a piece of reinforcement, a block or a plate is suitable - something that can probably be found in any garage or home workshop. To make a simple marking device, you can take a regular school ruler - wooden, plastic or metal.

Of decisive importance in the manufacture of the jig is the accurate calculation of the location of the holes on the workpiece. You can take ready-made diagram or make it yourself. The latter option is preferable, since the dimensions in the drawings must correspond to the tasks being solved.

Tools you will need:

• drill;
• grinder or jigsaw;
• a set of locksmith tools;
• clamps;
• vice.

When manufacturing a jig, you will need perfectly accurate drilling of guide holes and hardening of the finished device

Drawing of a homemade conductor for drilling holes for confirmations

Manufacturing stages

Let's consider the process of creating a metal conductor device for confirmations. This fastener is most often used when assembling furniture:

• from metal bar square section(10x10 mm) using a grinder, cut a piece of the required length. The ends of the resulting segment are leveled and cleared of burrs using a file. Corners and edges can be rounded for ease and safety of use;
• The hole locations are marked on the workpiece. Their centers should be located at a distance of 8 mm from the side edge (the thickness of the chipboard sheet is 16 mm). There should be 32 mm from the end and between the holes, in accordance with the generally accepted system of furniture fastenings. For marking, you can use a carpenter's angle or caliper. It is better to make marks on the part using a sharp metal object - an awl or a large needle. You can use a core and a hammer to make holes for the initial installation of the drill. When drilling holes, it is important to prevent the drill from moving and make them strictly perpendicular to the surface of the workpiece;
• use a drill with a diameter of 5 mm to make holes;
• to create a stop, you need to cut a piece of the required length from a metal plate (1x25 mm);
• sand the edges with sandpaper;
• bend the workpiece at a right angle, holding it in a vice. Fold the parts, aligning them coaxially;
• fasten the parts in this position using a clamp;
• From the side of the plate along the length of the device and at the end, drill holes corresponding to the size of the screw. Cut threads and fasten parts;
• Cut off the excess thrust plate and process the edges.

Video

In the process of assembling or repairing furniture, it is often necessary to carry out work on precise drilling of holes for confirmation, for dowels, dowels and other furniture fasteners. In the case of wood and chipboard, it is difficult to make such holes using an electric drill alone: ​​the entrance part of the hole is broken, and the hole itself may not be at a right angle to the mating surfaces. Thus, you will need a jig to drill the holes.

Purpose and classification of furniture conductors

The purpose of the jig for drilling holes is to accurately guide the drill to the required point and ensure the straightness of the tool throughout the entire depth of the resulting hole. In metalworking, such devices have been known for a long time, and are often supplied with the machine. Due to the increased number of closed connections in modern furniture products, the need for such conductors for woodworking specialists is very urgent.

There are the following types of furniture conductors:

1. Overheads that do not require fixation before use. They are simple, mobile, but force you to use only one hand when drilling (if the drill or grinder is not installed in a special frame). Making such a conductor with your own hands is easy and simple. They are used mainly when making holes in MDF or chipboards.
2. Rotary, which are equipped with folding brackets, and allow you to drill on two adjacent planes in one go.
3. Jigs for drilling holes at an angle. A highly specialized version of the jig, which is designed to make holes at different angles. Often combined with the overhead version of the equipment in question.
4. Sliding ones, with the help of which you can make several holes (including in several rows) without changing settings. More necessary for professionals who have to frequently perform similar works. Requires skills for proper use.

If the jig is sufficiently rigid, it can also be used for drilling holes in products that do not have a flat plane, for example, in pipes. Then the conductor is secured using a clamp (this option is not suitable for furniture, due to the risk of surface deformation).

DIY jig for drilling holes

Fundamentally, such equipment consists of the following parts:

1. An angular body element applied to the surfaces of products, which will subsequently be connected to each other with dowels, dowels or confirmations.
2. Guide bushings where the drill fits.
3. Clamping/fixing devices that are located at the end parts of the conductor.

For a conductor that is supposed to be made by hand, it is important to design the device for the most common mounting options for home craftsmen. If you need a universal jig (for furniture makers), then it is better to spend money on an industrial version of the equipment, which is characterized by increased accuracy of fixing parts and has a higher quality design. Moreover, manufacturers often offer templates, stops and other useful little things in the kit for the conductor. The price of an industrial furniture jig ranges from 500 to 1200 rubles, which is determined by its functionality - the length and number of guide holes.

Let's start designing a furniture jig for drilling holes by choosing a corner. There are more possibilities for a product where the corner will be unequal, and with the maximum possible thickness of the shelf. According to the assortment GOST 8510 “Unequal-flanged steel angles,” the minimum permissible dimensions of an angle L63 × 40 × 8: with a shelf thickness of 8 mm, a guide bushing with an outer diameter of up to 6 mm can be placed there. The internal hole for the drill, therefore, can be no more than 3.5...4 mm, but this is quite enough for most options for the resulting holes. As a last resort, they can be drilled out without using the device, especially if the hole is deep enough.

The next stage is the design of the guide bushing. It can be selected from any stainless steel pipe GOST 9941 (seamless) or GOST 9940 (all-welded). It is recommended to first select the pipe according to the diameter of the internal hole. A 6×1 pipe will allow you to obtain an internal hole for a drill with a diameter of up to 3.6...3.7 mm, and a 6×1.5 pipe will allow you to obtain an internal hole for a drill up to 2.7 mm (a two-sided gap is taken taking into account the thermal expansion of the material). The length of the sleeve must be no less than twice the height of the hole made in the corner. Each bushing must fit into the hole with an interference fit or transitional fit. The most appropriate is a fit according to the shaft system, when the already known outer diameter of the bushing is taken as a basis, and a hole is drilled for it in the corner. It is better to use a slight interference fit, for example h9/P10.

It happens that the jig needs to be designed for drilling a deep hole. In such cases, the bushing must be stepped (with a shoulder). Bushings for machine tools in accordance with GOST 12214 have the necessary accuracy and dimensions, the internal hole in which has a constant diameter over the entire height of the bushing.

The number of holes, and especially the distance between them, is selected according to the specific needs of the user.

When choosing a conductor mounting method, choose one of the following options:

• A spring stop that will press the surface of the jig to the part due to the elastic forces of the material. Any flat spring with the required clamping force will be suitable as such a stop;
• Fixation using self-tapping screws, which are screwed into the material of the part and keep the jig from being displaced by friction forces. This option is convenient in that the resulting outlines can then be used as additional elements for centering the future hole. In the case of chipboard, this option should be used with caution;
• External clamps, under which you should place corrugated rubber gaskets. In this case, the weight of the conductor will increase, and the compliance of the rubber may disrupt the perpendicularity of the axis of the conductor bushings. Therefore, using this method of fastening, first insert a drill into the sleeve, mark a hole, and only after that use clamps.

Jig for drilling for dowels and confirmations

The sequence and design of the simplest devices for accurately producing holes is discussed using the following two examples:

1. Multi-position jig with clamp fastening (see Fig. 1). The initial body part here is a thick-walled aluminum corner. Due to the considerable length of the device, an intermediate fastening is provided in the middle. When turning the jig at an angle of 90º, the increased wall thickness of the angle, which is superimposed on the surface of the part, is successfully used. The distance between the guide bushings is selected according to the most common distances for dowels or for confirmation.

Figure 1 — Multi-position jig for drilling holes with clamp fastening

1. A two-slider furniture jig, with which you can make holes in two mutually mating parts. The design of the device is clear from the attached drawing (see Fig. 2). It consists of two guide rulers, which are connected by fasteners to a connecting strip. The presence of several holes on it allows you to install the bar on parts of different widths. Replaceable housings with a set of guide bushings with different distances between them move along the rulers. The conductor is fixed using a connecting strip, and on the opposite side - with a travel limiter, which is tightened with a wing screw.

Precision drilling, used to connect wooden, metal and other elements to each other, is the key to the fact that the product will be of high quality, without backlash, durable and will be used effectively long time. When processing chipboard, OSB, MDF and other materials, it is recommended to use a drilling jig to achieve successful results.

Need for an assistive device

A do-it-yourself drilling jig helps both in domestic conditions and during industrial processing. This product is a thick metal strip. It has several holes, inside of which there are special bushings - sleeves.

Template makers can be manufactured in different options, but everyone has the same task - marking for drilling

A step-by-step algorithm that involves using a jig to drill holes in workpieces consists of the following steps:

• determine the drilling location;
• apply a conductor to it;
• fix the device in a convenient way;
• We put sleeves in the holes;
• drill in the indicated places.

Classification of markers

A jig for drilling holes with your own hands is used in various fields production activities. Based on similar characteristics, similar auxiliary devices are usually divided into several groups:

Jig for drilling holes

An overhead jig with a turret head is suitable for drilling standard holes for dowels of any size

The group is called this way because of the way it is operated. The product is usually installed on top of the intended workpiece and fixed using screw clamps. Less often, at home, it is based on an emphasis on any plane. This way you can mark holes for furniture screws.

Rotary jig for drilling holes

This jig is used for drilling at an angle. Comfortable processing is achieved due to guide bushings.

Tilting jig for drilling holes

Tiltable for use on multiple surfaces

The group is involved in drilling on several surfaces located at an angle to each other.

Sliding jig for drilling holes

They are in demand in areas where it is not possible to fix the marker. The guide bushings are mounted on folding bars.

Not only jigs are widely used for drilling holes for confirmation, but templates are also used in mechanical engineering, when it is necessary to make many of the same type of drills in workpieces.

This device has many advantages:

• it is possible to achieve maximum accuracy in finished products;
• ease of operation;
• the ability to repeat the center distance on any surface at a convenient time;
• affordable price finished product;
• can be done homemade conductor for any workpieces and different center distances.

Scope of application

During the furniture assembly process, some drawings indicate where to drill holes where the pins will be located inside. In such a situation, you cannot do without an accurate tool. It will not be possible to align the mates on the parts being connected as clearly as possible with simple markings, so a furniture jig will be useful for drilling holes.

Even a simple device in the form of a strip with a stop greatly facilitates and speeds up the process of making holes of the same type

In addition, the templating engine facilitates quick detection of the required points after the marker is located. In addition to holes for dowels, cavities for installation are also needed door hinges. They can also be made using a rigid stencil.

Marking and drilling multiple holes at an angle or perpendicularly, at the end or on the main surface in a pipe without help is always problematic. This is due to the special geometry of the workpiece. You can also save time and get the desired result thanks to the conductor. The set of auxiliary devices can be supplemented with an installation that ensures perpendicularity of the drill entry.

The difference between store-bought and homemade

The importance of this equipment, which performs an auxiliary function, cannot be overestimated. Some people prefer to do it with my own hands so that the product has the necessary functionality and is suitable for a specific job. Other experts strive to choose the most comfortable product from the products offered in online stores.

When purchasing, you need to pay attention to the manufacturer. The final price tag depends on the capabilities of the template. At home, it is enough to use household units, but for daily operations it is worth acquiring a professional product.

Making it yourself doesn't take much time. Also suitable materials always at hand.

Homemade device

It must be taken into account that this device includes a certain number of parts:

• body corner element, which must be applied one by one to the workpieces intended for connection with dowels or self-tapping screws;
• guide bushings-sleeves through which the drill will pass during the drilling process;
• fasteners providing strong connection tool with workpieces through a screw or cam connection.

A homemade template should include drawings and markings that are most often found at home on furniture and other areas. You will need to stock up on special stops to help with the work. average cost finished samples will cost about 500-1000 rubles. The difference between them is the dimensions, functionality and the number of guide bushings.

How to make a jig for drilling holes with your own hands

Design begins with choosing a corner that will serve as a base blank. It is preferable to choose a base with different sides, as well as the greatest possible thickness of the metal. According to GOST 8510, the most acceptable products will be those with side parameters of 63x40 mm and 8 mm thick. With such overall dimensions, it will be possible to use bushings 6 mm long, and there will be internal space for a drill of no more than 4 mm in diameter.

In most cases, these values ​​are enough to make your own template with your own hands. Additionally, you will need bushings, which at home are usually cut from stainless steel, corresponding to GOST 9941 or GOST 9940 for seamless and all-welded pipes, respectively.

The choice should begin by selecting a tube according to internal section. Usually the 6x1 mm format is used, which makes it easy to use a drill with a diameter of 3.6-3.7 mm. It is important to follow the rule that the minimum length of the sleeve can be twice the outer diameter of the tube.

The liner is seated with a slight interference fit or in a transitional format. It makes sense to do it in a shaft system, because the basis will be a stable outer diameter of the tube. It is for this that the voids in the corner are drilled. It is worth using the h9/P10 fit.

In some cases, a scriber is required to make sufficiently deep holes. This technique involves the presence of a stepped sleeve with collars. Strict GOST 12214 determines the parameters for machine jigs.

How many sockets to drill and how to position them is determined by the owner of the tool independently according to his needs. Traditionally, one of the following mounting options is chosen:

• using a spring-loaded stop that presses the jig to the part thanks to the elastic material;
• You can firmly fix the conductor using self-tapping screws, but when working with chipboard and similar materials, you should refrain from this method;
• external clamps, under which there are rubberized gaskets for safety purposes.
