What is better hitachi or bosh. Which screwdriver is better than Makita or Hitachi? Distinctive features of Hitachi in the example of this video

When choosing a tool, especially such as a screwdriver, the question immediately arises of which manufacturer to choose, because there are a great many of them on the market now.

Of course, this question cannot be answered unambiguously, and here it is worth sorting out in the technical characteristics of the tools. But this article will short review most popular brands screwdrivers, and also, it is worth deciding for what purposes a screwdriver can be used, and already from this we can conclude which model is more suitable.

Before determining which company to choose a screwdriver, you must first think about which model will be purchased professional or household. A lot of tool manufacturers produce household models that do not have too high power and will not be able to long time work without additional recharging. If the work will be carried out at home and not too often, then this model may well be suitable for domestic conditions. In this case, you will not need to overpay for a screwdriver that will have too much power.

The most popular models on the market have recently become Makita and Hitachi screwdrivers. And it was they who took the strongest positions in the markets, and showed their models to be of high quality and reliable. The cost of such models ranges from 2500 rubles. But here you should not throw other models of screwdrivers, and do not think that they are of too low quality. Yes, many companies can offer their models of screwdrivers from 700 rubles and very good performance.

Of course, you need to approach the choice of a professional screwdriver more responsibly, because labor productivity will immediately depend on it. Also here the question immediately arises of which company to choose a screwdriver, and even here you can answer Makita and Hitachi. Such professional tools will have high power and battery capacity. And in these models, the main difference is additional functions, this is backlight, engine cooling, reverse and much more. Any professional equipment and tools will cost too much. But not always such costs can justify their quality, that is, it is better to purchase a cheap tool that can last more than one year.

Unambiguously answer the question, which screwdriver is better, the answer is not found. But if you pay attention to manufacturers, then you can also get confused here, because now manufacturers present many models that can be both the cheapest and very expensive. But still, it is worth taking a closer look at Hitachi and Makita screwdrivers, here you can choose both a household tool and a professional one that will not fail in work.

Both experienced and novice craftsmen regularly face the problem of choosing a tool. You can, of course, ask around colleagues, but how many people - so many opinions. In this review, we will try to be as objective as possible and compare two world famous brands. In single combat, two Japanese will meet - and. These are companies from century history and vast experience in the manufacturing industry.

Range

Power tools are just one branch of the giant Hitachi Corporation. The company is also known for its electronics, climate equipment and heavy construction equipment: excavators, cranes, etc. The power tool line covers all popular categories. Less represented hand tool, machine tools and pneumatics.

Now the manufacturer is updating the range with battery technology: screwdrivers, planers, angle grinders, as well as garden trimmers, blowers and brush cutters. A series of tools with advanced brushless motors has been launched - you can recognize it by white color corps. Separately, Hitachi should highlight the line of generators. 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 rotary hammers alone, there are more than 20 models. Not forgotten and specialized tools: diamond and band saws, concrete compactors, etc. More attention is paid to 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 Hitachi or Makita, this tool is designed for heavy use and demanding tasks.

Popular Models

Hitachi or Makita, like any other manufacturer, can have their ups and downs. This is most evident in specific products. Take, for example, one of Hitachi's most popular cordless screwdrivers, the DS12DFV3. The model is completed with 2 batteries, well lies in a hand and is exceptionally reliable.

The Hitachi DH24PB3 rotary hammer, a lightweight two-mode model, was also in great demand. The only disadvantage of the tool can be called an inconvenient location and tight travel of the switch. In the new models, this defect has been eliminated.

One of the most successful models from Makita is the HR 2450 three-mode rotary hammer. Its power, ergonomics and functionality deserve the highest praise. From the Bulgarians can be distinguished light model Makita GA 5030 with 125mm disc. The tool differs in convenience, maneuverability and low vibration.

findings

So, we compared the two brands according to several criteria. Both companies come 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, Makita is among the leaders in the Russian market, while Hitachi is noticeably behind. In favor of Makita, we can say that the company provides a generally more consistent quality, affordable spare parts and best service. However, some models of Hitachi power tools are an enviable success, so this manufacturer should not be discounted.

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

Hello dear readers! Since you are reading this material, it means that you are almost certainly planning, or are already doing repairs at home. Perhaps you want to assemble a drywall ceiling, or maybe you decide to build a cat house on your own or a gazebo in the yard ...

In order to work effectively and get good result, you will need good tool. Particularly the screwdriver. In this article, we will understand what it is, what it is for, and, most importantly, how to choose a screwdriver.

Of course, we will consider a cordless tool, since it is 100,500 times more convenient, and not simple screwdrivers that can only tighten screws, but drill-drivers. If only because the simple ones are not for sale anymore. D-Sh, as you understand, can also drill, but where in the repair without it?

A screwdriver is a special hand-held power tool, which is important, with adjustable torque. It is designed for tightening (and, of course, loosening) screws, self-tapping screws, screws and all such 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?

Brand
Dimensions, shape, ergonomics
Battery capacity and type
Torque, impact function
Drilling diameter of various materials
Supply voltage
Contents of delivery

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

Screwdriver manufacturers worldwide

Most construction 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)
Bison (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 the above is still produced in China. But from my own experience, I can say that it is certainly not bad. Disputes do not subside, which is better: Bosch or Makita, Hitachi or AEG ... I will express my personal opinion. Bosch makes mediocre things at a pretty 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, in the new models they have a lot of smart electronics crammed in, like an electronic torque limiter.

Makita is a recognized middle ground, and it is believed that their tool is the best in terms of price / quality ratio. They are especially good with screwdrivers. I am of the same opinion at the moment. I have a puncher and a Makita Shurik - there are no problems. Moreover, I am not distinguished by any care for technology in this regard. Makita is rumored to be making 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, only once worked with their grinder. But quite recently, my father bought their D-Sh for himself, and I can say that the unit is more than worthy, for its price. For 5500 rubles, it has 2 Li-Ion batteries of 1.5 Ah, 14 V power supply, 36 Nm torque and even built-in batteries led indicator charge! I like it. So I do not rule out buying an instrument from AEG in the future.

American brands are not very popular with us. I think it's because of the prices. Or maybe it's the service.

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

No costs for the first two years of tool life. Even if something breaks, 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 use of the tool, the owner pays a maximum of 33% of its price for repairs.

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

For the house, just the thing is Interskol. Inexpensive and good quality equipment. Yes, it looks dumb, yes, relatively bulky, but it works. Nothing good has been written about Skil for a long time)) Sparky is also less and less common on sale.

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

Dimensions, ergonomics

This item is far from being important for every home master, but it is very relevant for pros who work with screwdrivers for hours. Let me tell you, size matters. But the meaning is twofold. On the one hand, a small screwdriver is better, the hand does not get so tired of it, it crawls 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 here, but a heavy tool easily sticks self-tapping screws into profiles. And this is not just my observation.

And anyway, I personally support compact models. My Shurik is one of the smallest in the Makita lineup. And working with larger models is no longer so comfortable for me. But I use them mainly on the installation of GKL. For those who work with wood or often drill, large and powerful models are more suitable.

Sharp corner at Bosch

Now about ergonomics. The first step before buying is to take the tool in the palm of your hand and pay attention to the handle. The main scourge of many models is the sharp angle between the “barrel” and the handle. The consequences of such a seemingly trifle is a stable callus between the thumb and forefinger.

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 jamb allowed by the developers of the tool. The speed switches for the vast majority of screwdrivers are located the same way - from above. There are only inconvenient buttons for switching the direction of rotation. On my Makita, for example, you can’t just press the right button - it’s too close to the palm of your hand, and the button itself is too small.

By the way, you can see one of the shortcomings of Makita in the photo above. He is only a year old there, I look like he is 40 years old)) If you clean it, then 30. It infuriates that it is completely japanese instrument, and the inscription "Makita" is all peeled off, as are the inscriptions of the torque limiter divisions on the case.

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 fully discharged state.
Low price
Frost resistance
Recovery after long-term storage

Disadvantages:

Relatively short life time - about 1000 charge / discharge cycles
Relatively low specific capacity (up to 2 Ah)
"Memory effect" - the battery can only be charged after it is completely discharged, otherwise its capacity in the next cycle will decrease by the amount of underdischarge
High self-discharge - they charged it, put it in a suitcase for a week, took it out - but the battery is low
Harm to environment- a controversial, 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

Disadvantages:

Even shorter life than NiCd - 500 cycles
Higher price compared to NiCd
High self-discharge (up to 10% in the first 24 hours after charging)
Cannot be stored fully discharged
Sensitivity to negative temperatures

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

Advantages of lithium-ion batteries for screwdrivers:

Very high specific capacity
Virtually no "memory effect"
Minimum self-discharge (20% per year for a fully charged battery at room temperature)
Minimum charge time (my batteries charge in half an hour)
3-4 times longer life than NiCd batteries

Disadvantages:

High price (not only batteries, but also a charger)
Inability to start charging when fully discharged (various control systems are built into modern batteries, so this drawback is eliminated)
High sensitivity to negative temperatures

Compact Li-Ion battery

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

Another the most important parameter batteries - capacity.

Most budget models of screwdrivers 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 get infected in a maximum of an hour, you will never be idle. Even if you drill wood or metal without interruption (and this is best done conventional drill, agree), then discharge such a battery in just about an hour.

Who needs 2 or even 3 Ah batteries is the happy owners of "Thor's hammers" - mega-powerful impact screwdrivers. They are so cool that they come with a handle, like perforators! There is also another special caste of "shuriks" - special tool mainly for drilling wood and metal. They have a cartridge rotation speed of up to 4000 rpm, while conventional machines, on average, up to 1300 rpm.

I present to your attention a video that tells about the criteria for choosing a screwdriver, it will be useful to see:

Impact, torque, drill diameters

As for the impact function, the overpayment for it is relatively small (500 - 1000 rubles), so the purchase of such a tool for the home seems to me quite justified. Of course, if you have a new building, and you 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 you to judge for what types of work the Shurik is generally suitable. Roughly speaking, KM reflects how powerfully the tool turns. 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 - generally beauty, they drill tiles with crowns without any problems. Anything above is already more for drilling metal and wood.

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

Supply voltage, delivery set

Screwdriver plastic case

Usually, the supply voltage directly determines the power of the tool. Here, the higher the voltage, the higher the maximum torque. I see no reason to explain in more detail.

As a rule, the delivery set of screwdrivers includes a plastic case (or bag) for carrying, 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 do not differ much from each other. But these kind of pleasant little things can play a decisive role in your choice. For example, if you choose from two similar models.

Chucks in the vast majority of models of screwdrivers are quick-clamping, convenient. For the spindle, forced braking is already used everywhere - when you release the trigger - the tool stops turning instantly, without any inertia. If there is no such brake in some model, do not buy it, this is the last century.

In conclusion, I can also tell you about one useful feature used in the coolest instrument models - pulse mode. The torsion in it occurs in measured jerks, which greatly facilitates drilling (the drill leads less to the side) and tightening / unscrewing self-tapping screws with a “killed” slot. For pros, this feature is very relevant.

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

Choose cordless screwdriver

In fact, most users of system tools prefer to have a universal tool in the household. 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 the shelves in the closet is obvious. But everything that exists has both its pluses and not its shortcomings; a non-universal battery-powered tool is no exception to this generally accepted rule. An apartment renovation website with its employees will tell you how to choose the right screwdriver for what to take into account. Share also your views, leave feedback.

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

Battery-powered tool provides autonomy from household power
The versatility of the tool provides ample opportunities for its implementation
Simplicity not precision work

And all this is a far from complete list of the abilities of universal tools. Manufacturers now offer a wide range different models cordless universal tools such as screwdrivers, grinders, planes and nothing else. In reality, there is a tendency to replace conventional corded tools with cordless tools, and not so much in everyday life, but in production and not in the industry. According to the text of the article, taking into account the relevance of the issue, right choice tool, carefully considered the properties not the characteristics of cordless screwdrivers.

Cordless universal tool - advantages and disadvantages

It goes without saying that the best choice of a tool is immediately determined by the tasks, the solution of which the tool should provide, not like the ladies, the criteria for its future operation (exploitation in everyday life in a different way, solving professional problems). A clear understanding of future operating criteria is all the more important, given that the price of functional household tools is not much different from the price of professional cordless screwdrivers. It is completely reasonable that the question arises - 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 a more gentle appeal.

These characteristics do not distinguish a professional model from a regular one, because some Russian) auto industry in the technical data sheets indicate that their product does not lose its performance after falling from a certain height. It should also be borne in mind that even in the circumstances of repair, a tool created for domestic needs is used less actively than in residential conditions. But such a high resource of strength and reliability is ensured due to functionality. Therefore, a professional tool is less functional than a household one.

For a clearer understanding of the essence of the issue, you need to analyze the situation by considering a specific example. Let's imagine that at some furniture shop a batch of universal cordless screwdrivers of the QUATTRO brand has arrived, who where is 4 screwdrivers in one brand BlackDecker KC2002FK.

On a superficial examination, it seems that the furniture creation was equipped with a lovely technique produced by famous brand, not here they saved a completely decent amount of money (the price of a set is 6000 rubles, although the instrument itself is not much cheaper). But this judgment is rather superficial. Cordless screwdriver: which one is better to choose, rating of 2017 professional models and for the home. Let's look at the question in more depth. In production, often for a day of work, you have to do the same type of operations in a different way to plan a tree, or to engage in the installation of finished products, as it is also called, to solve issues of product packaging. It is easy to guess that to perform these functions of the same type, only one tool is required (nettle, jigsaw, planer, screwdriver, etc.). It remains clear to our client if we compare the properties of a screwdriver with BlackDecker KC2002FK bits and not the properties of a separate tool. Choose) the myth of a universal cordless screwdriver for those who need to use individual components not so rarely, in addition, the myth itself is a tool.

For greater clarity, it makes sense to see the products that remain to be made to our client of the same brand, and directly the BlackDecker CP12K screwdriver, the price of which is 3.5 thousand rubles. A screwdriver of the KC2002FK type uses a battery with a capacity of 1.5 Amp / h not with a voltage of 14.4 V, although in a non-universal model a battery with a capacity of 1.5 Amp / h is not used with a voltage of 12 V, no matter how annoying it sounds, its torque is 16 Nm, and more massive universal screwdriver only 10.5 Nm. 1st significant sacrifice to ensure the versatility of the device.

A universal tool is not used as a jigsaw, to which, ladies like it, it is not purposeful to make special demands. The jigsaw of the same company KS999EK has a power of 600 W, and the adjustable frequency of blade strokes varies from 0 to 3200 strokes / min.

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

To whom the best option will choose this instance? Universal screwdriver with nozzles BlackDecker KC2002FK is an impeccable tool for do-it-yourself operation, in which it is used only for incidents beyond its control, in other words, 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.

How to choose the right cordless screwdriver

After considering the main parameters of universal cordless tools, let's dwell carefully on the choice of a cordless screwdriver, while looking at the characteristics that will allow the tool to be used not only at home, but also for commercial purposes.

We will limit our consideration to products equipped with NiCd batteries, which in reality are in great demand, because, despite our client's advantages, Li-Ion batteries, due to their own highest price, are not particularly popular. Cordless screwdriver: which one is better to choose, rating of 2017 professional models and for the home. The main parameters that you should pay attention to your own professionalism in the process of choosing a tool are:

The tool is equipped with 2.7 batteries with a voltage value of more than 2 12V
The presence of a charger capable of returning the model to working capacity in 1 hour
Equipping the tool with a huge number of steps (puffing forces) with the use of which the torque frequency is adjusted
highest value torque
The type of chuck that the tool is equipped with
Multiple rotation speeds

It is recommended to get acquainted closely with the warranty card, because some Russian) auto industry does not provide a guarantee for car batteries. It is better that additional equipment includes a set of nozzles in its abilities, 3 batteries, not a flashlight.

Armed with all the necessary knowledge, we will evaluate the pros and cons 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 not an impact option.
Brand cordless screwdriver Hitachi DS12DVF3 equipped with flashlights.
Brand cordless screwdriver BOSCH GSR 12-2 Professional.
Cordless screwdriver METABO BSZ 14.4 Impulse, at a price of 7 thousand rubles, which does not own the rather rare option "impulse"

Unfortunately, due to the exchange rate, the price has become not relevant, it is not introductory

Appreciated by the ladies, what remains to be done by our client is that the tools chosen for consideration are of the highest quality, reliability and durability. Although what remains to be done by our client, the screwdrivers listed above belong to the category of professional tools, at a price they are fully accessible to the average user, now we will take a closer look at the properties, do not decide which one to choose is better.

Cordless screwdriver Makita 8281DWPE

The tool is powered by 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 to working capacity in just one hour. The speed of the screwdriver is divided into 3.5 spectra: the 1st speed range includes speed values from 0 to 400 rpm, and the 2nd range from 0 to 1300 rpm.

screwdriver equipped with a keyless chuck (10 mm), equipped with 16 torque settings ( highest value 36 Nm) and the weight of the tool is 1.7 kg. Apart from typical operations, the tool is equipped with a shock option, it cannot perform from 0 to 18 thousand strokes per minute.

As a disadvantage of the tool it is natural to indicate the following:

For a tool equipped with a percussion function, the manufacturer supplied it with a rather weak cartridge
Low battery capacity (only 1.3 Ah), which is not enough for intensive work
It is possible to block the ventilation holes created to cool the electric motor during operation while working in the shock mode, while the ventilation holes are placed so unsuccessfully that they will certainly be blocked if the passage of the user's wide palms
The gearbox housing of a screwdriver equipped with an impact function is best made of metal.

Hitachi DS12DVF3 Cordless Screwdriver

The instrument is made with 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 tool, not, with, exotic linings protect the tool from falling. Moreover, the pads also provide the necessary ergonomics for the screwdriver handle (the user's hand is protected from vibrations and does not even sweat during heavy work).

BOSCH GSR 12-2 Professional Cordless Screwdriver

The tool is widely known in our country, not externally made in the classic style for the BOSCH company. The product rotation speed spectrum consists of 4.5 sub-ranges, speaking directly:

1st sub-range from 0 to 400 rpm
2nd sub-range from 0 to 1200 rpm

The technical equipment of the tool includes a keyless chuck (10 mm), covering the handle of the product with a shock-absorbing pad for 25 steps of torque setting, the maximum value of which is 27 Nm. The delivery set includes 4 batteries with a capacity of 1.5 Ah, not a charger, which restores the product's performance in 1 hour.

Lack of lining on the back of the tool body
Somewhat unsuccessful placement of the cartridge, which becomes a prerequisite for inconvenience when replacing a replaceable 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, additionally allows you to use a lot of torque, the value of which is 55 Nm. The product rotation speed spectrum consists of 5 sub-ranges, speaking directly:

1st sub-range from 0 to 400 rpm
2nd sub-range from 0 to 1400 rpm

The tool comes with a non-3.2 battery charger.

The main disadvantages of a screwdriver are:

Several dimensional body
A huge button for fixing the battery module, which can be a prerequisite for some inconvenience during operation
Poor placement of vents at the bottom of the tool, which will quickly become clogged in high dust environments

After analyzing the pros and cons of the considered models, we summarize our consideration in the final conclusions. The most powerful tool METABO BSZ 14.4 Impuls, equipped with a useful “impulse” function, offers the user enormous abilities, no matter how annoying it may sound to him. highest price not weight (2 kg), obviously do not contribute to the popularity of the instrument. The abilities of BOSCH GSR 12-2 Professional screwdrivers are not Makita 8281DWPE approximately the same. Note that more low value torque of the BOSCH brand screwdriver is one hundred percent compensated by the capacity of the batteries and, as it should, a longer operating time. The Hitachi DS12DVF3 screwdriver, apparently, is able to provide maximum comfort during work, despite its own exotic design. Cordless screwdriver: which one is better to choose, rating of 2017 professional models and for the home. Well-thought-out ergonomics of the tool contributes to the appearance of a sense of reliability and conviction, and the flashlight and accessories for attaching the model to a belt only increase the convenience of its use. The main advantage of the model is its moderate price, while at the same time the highest quality tool execution. The shortcomings of all 3 models is the "memory" of NiCd type batteries: there is an option to charge the batteries only when they are operable)) version of the discharge. Now draw conclusions, how to choose the right cordless screwdriver You understand better than others, choose suitable option from the above, do not forget about safety while working with inventory. Fortuny in operation, as well as leave your feedback!
