Which jigsaw brand is better: Bosch, Makita or Hitachi. Which screwdriver is better: Hitachi, DeWalt or Bosch? Protection against disc wedge

When purchasing a new jigsaw, we must choose one of the many models presented. Models differ in power, weight, technical characteristics and of course – the same price. But besides this, they are produced by various manufacturers.

Of course, those who already use a trusted manufacturer will choose such a manufacturer, but if you are buying such a tool for the first time, then discarding the cheap and non-durable disposable models from little-known companies, we suggest you focus your attention on three more practical manufacturers - Bosch, Makita or Hitachi .

It is worth noting that there are professional tools that are more expensive, from manufacturers such as FESTOOL, Mafel, Protoo, but they are very expensive and are needed only by professionals, so we will focus on more affordable models, in terms of price. It should also be said that in terms of quality of work, these models are quite competitive with the above-mentioned ones in many tests.

Looking at the price, it is worth noting that blue Bosch is perhaps the leader if it is not assembled in China or Russia. In principle, price is the first and more correct indicator of the quality and reliability of a tool. To this it is worth adding a well-established brand.

Bosch jigsaws are more balanced and are considered the best tool among all jigsaw companies in this category, as they have achieved the highest level and comfort when making a cut. In addition, models such as GST 135 CE and GST 135 BCE are equipped with a “Precision Control” system, where, with a simple press of a button, the guides are automatically adjusted to different thickness saw blade for precise guidance and neat corner cuts.

Now let's talk about Makita jigsaws, despite the simple, not outstanding design, all models are designed quite well and the strictly horizontal handle lies securely in the hand. These jigsaws are highly reliable and cope with any task just as well as Bosch jigsaws. The indicators are approximately the same, but the price is lower, so not everyone wants to pay money for a more popular brand.

Makita, like its predecessor, has a minimal level of vibration, it does not jump on the surface, and does not strain the hand. When cutting, it moves easily and clearly. If you read the reviews, they talk about the reliability and durability of the tool. Despite the fact that Makita appeared on the market later, it has long established itself as a best manufacturer professional tool.

The Hitachi company is less familiar to us, but I would like to note great design, even too ultra, a modern body, which is covered mainly, on most models, with rubber, which is pleasant to the touch, but unfortunately is not very good to clean after cuts. When studying the reviews, you will find out that it is not very well thought out to protect the engine from small sawdust and when sawing materials made from small particles, for example, the chipboard gearbox becomes clogged with chips and dust.

I must say that many are shocked by the new constructive solution plastic holder for files, but it is made with high quality and no one reports any breakdowns, at the same time, this jigsaw weighs less than its predecessors. Otherwise, a Hitachi jigsaw with similar technical data is cheaper and this is also important.

Hello, dear readers! Since you are reading this material, it means that you are almost certainly planning, or are already doing, home renovations. Perhaps you want to assemble a plasterboard ceiling, or maybe you have decided to build a house for your cat or a gazebo in your yard yourself...

In order to work effectively and get good results, you will need good tool. In particular, a screwdriver. In this article we will figure out what it is, why it is needed, and, most importantly, how to choose a screwdriver.

We will, of course, consider cordless tools, since they are 100,500 times more convenient, and not simple screwdrivers that can only tighten screws, but drill-drivers. If only because simple ones don’t really sell anymore. D-Sh, as you understand, can also drill, but where would repair work be without this?

The screwdriver is a special hand power tool, which is important, with adjustable torque. It is designed for tightening (and, of course, unscrewing) screws, self-tapping screws, screws and all sorts of fasteners + for drilling holes. Outwardly it looks like a fat pistol.

Criterias of choice

Since this is not another useless female “rag”, but a modern complex mechanism, as a rule, people take its choice seriously. What criteria are important when choosing it?

1. Brand
2. Dimensions, shape, ergonomics
3. Battery capacity and type
4. Torque, impact function
5. Drilling diameter of various materials
6. Power supply voltage
7. Contents of delivery

Let's go through each of these points in more detail.

World manufacturers of screwdrivers

In most hardware stores you can find products from companies such as:

• Bosch (Germany)
• Makita (Japan)
• AEG (Germany)
• Hitachi (Japan)
• Hilti (Liechtenstein)
• DeWalt (Germany)
• Black & Decker (USA)
• Metabo (Germany)
• Interskol (Russia)
• Zubr (Russia)
• Sparky (Germany)
• Skil (Netherlands)

As you can see, the choice is mega-large, but I want to warn you right away that most of of the above are still produced in China. But from my experience I can say that this is certainly not bad. The debate continues about which is better: Bosch or Makita, Hitachi or AEG... I will express my personal opinion. Bosch makes things that are mediocre in terms of performance at a fairly high price. But, in general, the tool of this company lasts a long time. And this is from the experience of my colleagues. Metabo is about the same. Although, it seems like the new models are packed with a lot of smart electronics, like an electronic torque limiter.

Makita is the recognized golden mean, and their instrument is considered to be the best in terms of price/quality ratio. They are especially good at screwdrivers. I hold the same point of view on this moment and I. I have a hammer drill and a Makita shurik - no problems. Moreover, I am not distinguished by any concern for technology in this regard. Rumor has it that Makita makes screwdrivers for NASA astronauts. Hitachi has about the same image, perhaps a little simpler.

Until recently, I almost never saw the AEG tool in people’s hands; I only used them once with an angle grinder. But just recently my father bought himself their D-Sh, and I can say that the unit is more than worthy, for its price. For 5,500 rubles, it has 2 Li-Ion batteries of 1.5 Ah each, 14 V power supply, 36 Nm torque and even an LED charge indicator built into the batteries! I like it. So I don’t rule out purchasing a tool from AEG in the future.

American brands are not particularly popular here. I think it's because of the prices. Or maybe it's a service issue.

Hilti, in my understanding, is a show-off scam. Expensive price, average characteristics. Their trick is some special warranty and service conditions, but on the other hand, again, I heard that their tools break not so rarely. For example, what Hilti gives:

• No costs for the first two years of tool life. Even if something is broken, a representative of the company will personally come to you, take the tool from you, fix it for free and deliver it back to you
• Lifetime manufacturer's warranty
• After two years of service of the instrument, the owner pays for repairs a maximum of 33% of its price

Of course, all this is very cool, but for the money they ask for their instrument, you can buy 2-3 Makitas with similar characteristics. And buy Hilti for home use- generally nonsense. Where it will be appropriate is at construction sites, where the tool is taken by everyone, where it is dropped, knocked, etc. There he will live longer than the others, and the guarantee will come in handy.

Interskol is just the thing for the home. Inexpensive and fairly high-quality equipment. Yes, it looks a little awkward, yes, it is relatively bulky, but it works. They haven’t written anything good about Skil for a long time)) Sparky is also becoming less and less common on sale.

As for the prices of screwdrivers, if you need a high-quality, but at the same time simple tool for installation, for example, plastic panels in the bathroom at home, expect a price of 3000 - 4500 rubles. Almost all Interskols, several Makita and Hitachi go at this price. Everything that costs more is mostly useful to professionals.

Dimensions, ergonomics

This point is not important for everyone. home handyman, but is very relevant for professionals who work with screwdrivers for hours. I will say this - size matters. But the meaning is twofold. On the one hand, a small screwdriver is better, it doesn’t tire your hand so much, it fits into hard to reach places. But, at the same time, it is more difficult for them to tighten the self-tapping screw!

I don’t know what exactly is the matter, but a heavy tool easily inserts self-tapping screws into the profiles. And this is not just my observation.

And all the same, I personally am a supporter of compact models. My “Shurik” is one of the smallest in model range Makita. And I’m no longer so comfortable working with larger models. But I use it mainly for installation of gypsum boards. For those who work with wood or often drill, large and powerful models are more suitable.

Bosch has an acute angle

Now about ergonomics. The first thing you should do before purchasing is to take the tool in your palm and pay attention to the handle. The main scourge many models - an acute angle between the “trunk” and the handle. The consequences of such a seemingly trifle are a stable callus between the thumb and index finger.

Obtuse angle on a Makita screwdriver

My “sidekick” has this angle obtuse (almost straight), and I don’t have any calluses.

This is perhaps the main potential flaw made by the tool developers. The speed switches for the vast majority of screwdrivers are located the same way - on top. There are only inconvenient buttons for switching the direction of rotation. On my Makita, for example, you can’t easily press the right button - it’s too close to the palm, and the button itself is too small.

By the way, you can notice one of the Makita's shortcomings from the photo above. He's only a year old there, I look like he's 40 years old)) If you clean it, he's 30. What's infuriating is that it's completely japanese instrument, and the “Makita” inscription has all peeled off, as well as the inscriptions of the torque limiter divisions on the body.

Batteries

An extremely important criterion for choosing a screwdriver. Modern cars use 3 types of batteries: Nickel-cadmium (NiCd), nickel-metal hydride (NiMH) and lithium-ion (Li-Ion).

Advantages of nickel-cadmium batteries:

• This is the only type of battery that can be stored in a completely discharged state.
• Low price
• Frost resistance
• Recovery after long-term storage

Flaws:

• Quite short lifetime - about 1000 charge/discharge cycles
• Relatively low specific capacity (up to 2 Ah)
• “Memory effect” - the battery can be charged only after complete discharge, otherwise its capacity in the next cycle will decrease by the amount of underdischarge
• High self-discharge - charged it, put it in a suitcase for a week, took it out - but the battery was discharged
• Harm to environment- a debatable, of course, disadvantage

First of all, these batteries are still in demand only because of their low price.

Advantages of nickel-metal hydride batteries:

• Environmentally friendly
• Smaller dimensions compared to NiCd
• Mild “memory effect”
• High specific capacitance

Flaws:

• Life time is even shorter than NiCd - 500 cycles
• Higher price compared to NiCd
• High self-discharge (up to 10% in the first 24 hours after charging)
• Impossibility of storage when completely discharged
• Sensitivity to negative temperatures

Nickel-metal hydride batteries are now quite rare, because lithium-ion batteries are much cooler.

Advantages of lithium-ion batteries for screwdrivers:

• Very high specific capacitance
• Virtually no “memory effect”
• Minimum self-discharge (20% per year for a fully charged battery at room temperature)
• Minimal charging time (my batteries charge in half an hour)
• Service life is 3-4 times higher than NiCd batteries

Flaws:

• High price (not only batteries, but also the charger)
• Inability to start charging when fully discharged (modern batteries have built-in various systems control, so this drawback is eliminated)
• High sensitivity to negative temperatures

Compact Li-Ion battery

Of course, for the home there is no point in purchasing a tool with expensive Li-Ion batteries. NiCd will do just fine. But for the pros there is only one option - take Li-Ion. I have something to compare with, and if I have to buy a screwdriver again, I will only buy one with lithium-ion batteries.

Another important battery parameter is capacity.

Most budget screwdriver models are equipped with 1.3 Ah batteries. If we take as an example the work of assembling a plasterboard ceiling at an average pace, then the charge of one (new) battery will last for 3-4 hours, no less. Considering that modern batteries become infected in a maximum of an hour, you will never be idle. Even if you drill wood or metal without interruption (and it’s better to do this a regular drill, agree), then discharge such a battery in just about an hour.

Who needs 2 or even 3 Ah batteries are the lucky owners of “Thor’s hammers” - mega-powerful impact screwdrivers. They are so cool that they come with a handle like a rotary hammer! There is also another special caste of “Shuriks” - special tool mainly for drilling wood and metal. Their cartridge rotation speed reaches 4000 rpm, while for conventional machines, on average, up to 1300 rpm.

I present to you a video that describes the criteria for choosing a screwdriver, it will be useful to watch:

Impact, torque, drill diameters

As for the impact function, the overpayment for it is relatively small (500 - 1000 rubles), so purchasing such a tool for the home seems completely justified to me. Of course, if you have a new building and need to make several hundred holes in concrete, a screwdriver will not help you; you will have to take a hammer drill.

The maximum torque allows us to judge what types of work the Shurik is generally suitable for. Roughly speaking, KM reflects how powerfully the tool twists. Normal specimens have a KM of at least 24 Nm (Newton meters), which is quite suitable for installing drywall and building a hut. 30 or 36 Nm is absolutely beautiful; they can drill tiles with crowns without any problems. Everything higher is more suitable for drilling metal and wood.

For example, a screwdriver with a torque of 36 Nm can drill wood with a drill bit with a maximum diameter of 25 mm. And a tool with a CM of 80 Nm is already 65 mm. The difference is obvious. The specifications always indicate the maximum diameter of drills for wood, metal and concrete, if it is impact. So figure out what you are going to drill and choose the right tool.

Supply voltage, delivery set

Plastic suitcase from a screwdriver

Typically, the supply voltage directly determines the power of the tool. Here, the higher the voltage, the higher the maximum torque. I see no point in explaining in more detail.

As a rule, the delivery package for screwdrivers includes a plastic carrying case (or bag), the tool itself, two batteries, a charger, at least 1 bit and instructions. Some manufacturers can supplement the kit with a flashlight, some with a set of bits. In this, manufacturers are not very different from each other. But these kinds of pleasant little things can play a decisive role in your choice. For example, if you are choosing from two similar models.

The chucks of the vast majority of screwdriver models are quick-clamping and convenient. For the spindle, forced braking is already used everywhere - when you release the trigger, the tool stops turning instantly, without any inertia. If some model doesn’t have such a brake, don’t buy it, it’s a thing of the past.

In conclusion, I can also tell you about one useful feature used in the coolest models of the instrument - pulse mode. Torsion in it occurs in measured jerks, which significantly facilitates drilling (the drill moves less to the side) and tightening/unscrewing screws with a “killed” slot. For pros, this function is very important.

Perhaps that’s all, we’ve learned a lot about how to choose a screwdriver. I also recommend scanning YouTube, there are a lot of different videos with specific models tool. I found my model)

Both experienced and novice craftsmen regularly face the problem of choosing a tool. You can, of course, ask your colleagues, but there are so many people, so many opinions. In this review we will try to be as objective as possible and compare two world-famous brands. Two Japanese will compete in single combat - and. These are companies with a hundred-year history and vast experience in the field of equipment production.

Range

Power tools are just one of the areas in the giant Hitachi Corporation. The company is also known for its electronics, climate control equipment and heavy construction equipment: excavators, cranes, etc. The range of power tools covers all popular categories. To a lesser extent, hand tools, machine tools and pneumatics are represented.

Now the manufacturer is updating its range with battery-powered equipment: screwdrivers, planes, grinders, as well as garden trimmers, blowers and hedge trimmers. A series of tools with advanced brushless motors has been released - it can be recognized by the white color of the body. Separately, Hitachi’s line of generators is worth highlighting. This is first class, reliable equipment.

Unlike its competitor, Makita deals exclusively with tools and equipment (both electric and gasoline). But its range is very diverse. For example, in the line of heavy hammer drills alone there are more than 20 models. Specialized tools have not been forgotten: diamond and band saws, concrete compactors, etc. More attention focuses on the introduction of technological innovations and the development of fundamentally new designs.

Purpose

The products of both manufacturers are addressed to professionals. Therefore, there is no doubt about its reliability and wear resistance. Whether it's a Hitachi or a Makita, this tool is designed to withstand heavy-duty use and challenging tasks.

Popular models

Hitachi or Makita, like any other manufacturer, can have their successes and failures. This is most clearly manifested in specific products. Let's take, for example, one of the most popular Hitachi cordless screwdrivers - DS12DFV3. The model is equipped with 2 batteries, fits well in the hand and is extremely reliable.

The Hitachi DH24PB3 hammer drill, a lightweight dual-mode model, was also in great demand. The only disadvantage of the tool is the inconvenient location and tight movement of the switch. This defect has been eliminated in new models.

One of Makita's most successful models is the HR 2450 three-mode rotary hammer. Its power, ergonomics and functionality deserve the highest praise. Among the grinders, we can highlight the lightweight Makita GA 5030 model with a 125 mm disc. The tool is comfortable, maneuverable and has low vibration.

conclusions

So, we compared the two brands according to several criteria. Both companies are from Japan, have been on the market for many years and produce tools for professionals. Quite a lot in common - but at the same time Russian market Makita is among the leaders, while Hitachi is noticeably behind. In favor of Makita, we can say that the company provides generally more consistent quality, affordable spare parts and better service. However, some models of Hitachi power tools enjoy enviable success, so this manufacturer should not be discounted.

The question of which is better in price - Makita or Hitachi - is also not easy to answer. Products belong to approximately one price segment, although on average Hitachi is slightly cheaper. We recommend choosing not a brand, but comparing similar models from 2 brands - this will allow you to make a more informed decision.

Choosing a cordless screwdriver

In fact, most users prefer to have construction tools in their household universal tool. The motives for such zeal are completely natural: it is more rational to have one tool in the household that can change several. The cost savings on closet shelf space are obvious. But everything that exists has both its advantages and its disadvantages; a universal tool powered by batteries is no exception to this generally accepted rule. The apartment renovation website will tell you how to choose the right screwdriver and what is best to take into account. Share your views and leave reviews.

Therefore, the user needs to have because when choosing a universal tool, he deliberately allows for the averaging of certain features according to which the quality of the tool is assessed, such as drilling speed or, in other words, impact force. Apart from this, some properties of the tool become simply incomparable; nettle drilling with impact does not drill holes of small diameter. Cordless screwdriver: which one is better to choose, rating 2017 professional models and for the home. But the user enjoys all the advantages inherent in versatility, such as:

• Battery-powered tool ensures autonomy of operation from household power supply
• The multifunctionality of the tool provides wide possibilities for its implementation
• Simplicity is not precision

And all this is far from a complete list of the capabilities of universal tools. Manufacturers now offer a wide range of different models of cordless universal tools, such as: screwdrivers, grinders, planes and more. In reality, there is a tendency to replace conventional corded tools with cordless tools, not so much in everyday life, but in production and not in industry. According to the text of the article, taking into account the relevance of the issue, the right choice tools, the properties and characteristics of cordless screwdrivers are carefully considered.

Cordless universal tools - advantages and disadvantages

It goes without saying that the best choice The tool is immediately determined by the tasks, the solution of which the tool must provide, not, like the ladies, by the criteria for its future operation (everyday use or the solution of professional problems). A clear awareness of future operating conditions is all the more important, taking into account that the price of functional household tools not much different from the price of professional cordless screwdrivers. It is completely reasonable for the question to arise - what is the difference between a professional tool and household models. The main difference is manifested in the fact that a professional screwdriver is able to withstand longer loads and more gentle handling.

These characteristics do not distinguish a professional model from a regular one, which is why some Russian automobile manufacturers indicate in their technical data sheets that their product does not lose its functionality after falling from a certain height. It should also be taken into account that even in the circumstances of repair, a tool created for domestic needs is used less actively than in residential premises. But this highest level of strength and reliability is ensured due to functionality. Therefore, professional tools are less functional than household ones.

To understand the essence of the issue more clearly, you need to analyze the situation by considering a specific example. Let's imagine that at some furniture workshop A batch of universal cordless screwdrivers of the QUATTRO brand has arrived, who knows where these are 4 screwdrivers in one of the BlackDecker KC2002FK brand.

Upon superficial examination, it seems that the furniture creation was equipped with wonderful equipment produced by a well-known brand, but they did not save a decent amount of money (the price of the set is 6,000 rubles, although the instrument does not cost much less). But this judgment is rather superficial. Cordless screwdriver: which one is better to choose, rating of 2017 professional models and for home. Let's look at the question more thoroughly. In production, often in a day’s work you have to do the same type of operations, plan wood, or do installation finished products, as it is also called, solves product packaging issues. It’s easy to imagine that to perform these same functions, only one tool is required (nettle, jigsaw, plane, screwdriver, etc.). It becomes clear to our client if we compare the properties of a screwdriver with BlackDecker KC2002FK attachments not the properties of a separate tool. The Myth universal cordless screwdriver is chosen by those who need to use individual components more than once, in addition to the Myth tool itself.

For greater clarity, it makes sense to look at the products that our client has to make of the same brand, and directly the BlackDecker CP12K screwdriver, the price of which is 3.5 thousand rubles. A screwdriver type KC2002FK uses a battery with a capacity of 1.5 Ampere/hour not a voltage of 14.4 V, although the non-universal model uses a battery with a capacity of 1.5 Ampere/hour not a voltage of 12 V, as annoying as it may sound, the value of its torque is 16 Nm, but a more massive universal screwdriver is only 10.5 Nm. The first significant sacrifice to ensure the versatility of the device.

The universal tool is not used like a jigsaw, for which ladies like it, there are no special requirements for it. The jigsaw from the same company, KS999EK, has a power of 600 W, and the adjustable speed of the blade strokes varies from 0 to 3200 strokes/min.

The attachment of the universal device shows the same stroke rate (3000 strokes/min), but with its help there is an option to cut material to a depth of up to 38 mm, and with a special jigsaw wood is cut up to 65 mm.

To whom the best option will choose this instance? The universal screwdriver with BlackDecker KC2002FK attachments is an ideal tool for DIY use, in which it is used only in cases beyond one’s control, that is, quite occasionally. Its introduction in production makes no sense, therefore, in the professional environment, special tools equipped with the same type of battery packs that do not perform strictly defined, standard functions have become widespread.

The optimal approach to saving money was shown by BOSCH, which released model line tools powered by the battery of a GSR 18 VE-2-LI Professional screwdriver. Note that the cost savings are very significant, taking into account the highest price of a modern Li-Ion battery. Thus, when purchasing an additional tool from this company, there is no longer a need to get an additional battery.

How to choose the right cordless screwdriver

After considering the main parameters of universal cordless tools Let's take a closer look at choosing a cordless screwdriver, while looking at the characteristics that will allow you to use the tool not only at home, but also for commercial purposes.

We will limit our consideration to products equipped with NiCd brand batteries, which are actually in wide demand, because, despite our clients having their advantages, Li-Ion batteries, due to their high price, are not particularly popular. Cordless screwdriver: which one is better to choose, rating of 2017 professional models and for home. The main parameters to which you should focus your own professionalism in the process of choosing a tool are:

• The tool is equipped with 2.7 batteries with a voltage value of less than 2 12V
• Availability of a charger capable of returning the model to functionality in 1 hour
• The tool is equipped with a huge number of steps (tightening forces) with the use of which the frequency of the torque is adjusted
• Highest value torque
• Type of chuck the tool is equipped with
• Multiple rotation speeds available

It is recommended that you carefully read the warranty card, because some Russian auto industry does not provide a warranty on car batteries. It is better that the additional equipment includes a set of attachments, 3 batteries and a flashlight.

Armed with all the necessary knowledge, we will evaluate the advantages and disadvantages of the following models of recognizable brands:

• Makita 8281DWPE, the cost of which is 5.8 thousand rubles, not equipped with a Li-Ion battery and no shock option.
• Cordless screwdriver brand Hitachi DS12DVF3 equipped with flashlights.
• Cordless screwdriver brand BOSCH GSR 12-2 Professional.
• Cordless screwdriver METABO BSZ 14.4 Impuls, priced at 7 thousand rubles and not owning the rather rare “impulse” option

Unfortunately, due to the exchange rate, the price is no longer relevant and is not for informational purposes only

They are appreciated by the ladies, what remains for our client to do is that the instruments chosen for consideration are distinguished by the highest quality, reliability and durability. Although what remains for our client to do, the screwdrivers listed above belong to the category of professional tools, at a price they are completely affordable for the average user, now we will take a closer look at the properties and decide which one is better to choose.

Cordless screwdriver Makita 8281DWPE

The power source for the tool is the latest generation Li-Ion battery with a voltage of 14.4 V, which is certainly its advantage.

The tool comes with 2 batteries charger, which restores the device’s functionality in just one hour. The screwdriver rotation speed is divided into 3.5 spectrums: the 1st speed spectrum includes speed values ​​from 0 to 400 rpm, and the 2nd spectrum from 0 to 1300 rpm.

Screwdriver equipped with a quick-release chuck (10 mm), equipped with 16 stages of torque setting (maximum value 36 Nm), and the weight of the tool is 1.7 kg. In addition to standard operations, the instrument is equipped with a blow option; it can perform from 0 to 18 thousand blows per minute.

As disadvantages of the tool It is natural to indicate the following:

• For a tool equipped with an impact function, the manufacturer supplied it with a rather weak cartridge
• Low battery capacity (only 1.3 Ah), which is not enough for intense work
• There is a possibility of overlapping by hand ventilation holes, created to cool the electric motor during operation in shock mode, while the ventilation holes are placed so unsuccessfully that they will certainly block if the user’s wide palms pass through
• The gear housing of a screwdriver equipped with an impact function is best made of metal.

Hitachi DS12DVF3 cordless screwdriver

The instrument has a somewhat exotic exterior design. This design is not accidental. That’s it, it’s simply not economically feasible to fake the body of the instrument, but exotic linings protect the instrument from falling. Moreover, the pads also provide the screwdriver handle with the necessary ergonomics (the user’s hand is protected from vibrations and does not even sweat during intense work).

The screwdriver is supplied with a flashlight, a charger that ensures the product’s functionality is restored in 1 hour, and a 1.4 Ah battery.

The screwdriver has 4.5 speed ranges: the 1st speed range includes speed values ​​from 0 to 300 rpm, and the 2nd range from 0 to 1100 rpm.

The screwdriver is equipped with a quick-release chuck (10 mm) and 22 torque settings.

When choosing, take into account the main disadvantages of the tool:

• An obsolete, although not very reliable drill chuck
• Unsuccessful fastening of the replacement bit to the bracket (the bat often gets caught on clothing)
• The reverse button is small, although its placement itself is quite comfortable for the user

Cordless screwdriver BOSCH GSR 12-2 Professional

The instrument is widely known among us and is made in the classic style of the BOSCH company. The rotation speed spectrum of the product consists of 4.5 subranges, speaking directly:

• 1st subrange from 0 to 400 rpm
• 2nd subrange from 0 to 1200 rpm

IN technical equipment The tool includes a quick-release chuck (10 mm), covering the handle of the product with a shock-absorbing pad, not 25 stages of setting the torque, the highest value of which is 27 Nm. The delivery set includes 4 batteries with a capacity of 1.5 Ah and a charger that restores the functionality of the product in 1 hour.

• No pad on the back of the instrument body
• Somewhat unsuccessful placement of the cartridge, which becomes a prerequisite for inconvenience when replacing the replacement tool

Cordless screwdriver METABO BSZ 14.4 Impuls

The equipment is equipped with a rather rare “impulse” option, which eliminates the need to use a core when drilling, and additionally makes it possible to use the torque, the value of which is 55 Nm. The product rotation speed spectrum consists of 5 subranges, speaking directly:

• 1st subrange from 0 to 400 rpm
• 2nd subrange from 0 to 1400 rpm

The tool comes with a non-3.2 battery charger.

The main disadvantages of a screwdriver are:

• Slightly oversized body
• The button for fixing the battery module is huge, which can cause some inconvenience during operation
• Poor placement of ventilation holes at the bottom of the tool, which will quickly become clogged in circumstances of high dust concentration

After analyzing the advantages and disadvantages of the considered models, we summarize our consideration in the final conclusions. The most powerful instrument METABO BSZ 14.4 Impuls, equipped with a useful “impulse” function, offers the user enormous capabilities, as annoying as it may sound, its high price and weight (2 kg) obviously do not contribute to the popularity of the instrument. The capabilities of the BOSCH GSR 12-2 Professional and Makita 8281DWPE screwdrivers are approximately similar. Note that the lower torque value of a BOSCH brand screwdriver is one hundred percent compensated by the battery capacity, which is not, as it should be, more for a long time work. The Hitachi DS12DVF3 screwdriver is apparently capable of providing maximum comfort during operation, despite its exotic design. Cordless screwdriver: which one is better to choose, rating of 2017 professional models and for home.

Screwdriver Championship in Kharkov

We are reporting from the Metalist stadium. Kharkov is holding a world championship among 14.4 Volt screwdrivers in terms of price-quality ratio. Three legendary models made it to the finals:

The first to enter the torque sector is the representative of the Land of the Rising Sun. It rests against the standard self-tapping screw, and... a brilliant result - 30 Nm! The stands are exploding! With such a torque, it can easily screw a 300 mm screw into a log.

Meanwhile, a representative from Europe is preparing to speak. Bosch GSR14.4VE-2 0.601.993.H20 clicks menacingly with its keyless chuck Auto Lock system, busily approaches the projectile, the stands freeze, the steel gears of the planetary gearbox tense, the self-tapping screw flies into the log, but the judges record the same result as the previous athlete - 30 Nm. Yes, it is impossible to buy our judges. Kharkov masters will not let anyone down!
An American athlete in a yellow and black aggressive suit goes to the start. DeWalt DC 731 KB in beautiful physical fitness. It’s clear that he doesn’t care about the cost of victory – he’s ready for anything! This is a turn, this is power! The self-tapping screw passes through the log with a grinding sound. The stands rejoice, anticipating victory. What result did the Kharkov judges record? Wow - 40 Nm! Unprecedented power. A good application for a world record...

Of course, no one will hold such a championship in Kharkov, but from the vast clan of screwdrivers (or cordless drills, to be precise) I would highlight these three models. They are significant in that they have the same battery voltage. This means they can be easily compared.
DeWalt is considered the “old guy” on the market. I had to deal with screwdrivers from this company back in the nineties. Very durable body. After falling from the second floor, he worked as if nothing had happened. The gearbox has two speeds. The lower one is good for tightening, and the higher one for drilling holes. The batteries are ordinary, nickel-manganese, but they have a good capacity - 2.6 A/h. There is also a fashionable thing today - LED lights. Convenient when working in places with poor visibility. The price of the “American” is about $250 and it is good for those who work, for example, on roofs.
Bosch GSR14.4VE-2 0.601.993.H20- This is a professional tool. I like it because its body is well balanced and it fits perfectly in the hand. The brushes can be replaced without disassembling the engine (a hint that the screwdriver will survive more than one such replacement). This device also has a two-speed gearbox, steel planetary gears, very smooth start and instant stop. The batteries are no different from the previous model. To be honest, I don't like nickel power supplies. They charge for a long time and have memory. I often found myself in situations where one battery was discharged, and the second had not yet been charged. The price of a screwdriver from the Bosch concern deserves respect - $270. It's perfect for interior work, for example, with drywall. It is often used by furniture makers.

It was not only Kharkov that conquered. Perhaps there is no city where the craftsmen do not squeal from this Japanese.
Even one consultant tried to mess with me, denigrating the entire series of screwdrivers from Hitachi. They say Lately Their batteries (lithium-ion, by the way) began to quickly fail. Judging by my experience with this tool, the seller simply wanted buyers to pay attention to other models. A chic screwdriver, thought out to the smallest detail! It is small and light. With him you can get close to the most problem areas. Power in combination with a two-speed gearbox and a 22-position force regulator is a real treat for the master. The battery charges in half an hour, and I have been working on my original batteries for three years now. I see no reason to deny myself the pleasure of owning this instrument. The price, by the way, is quite reasonable - $200. Good for both indoor and outdoor work.

However, before you buy a new screwdriver, I imagine different models in relation to the types of work that I mainly do. It is important for me to hold the tool in my hands myself, because price does not always determine ease of use, which is extremely important for a master.
