Choosing a cordless screwdriver

Almost the majority of users of construction tools prefer to have a universal tool in the farm. The motives of this desire are quite natural: it is more rational to have one tool on the farm that can replace several. Saving money and places on the shelves in the closet is obvious. However, all things have their own merits and their shortcomings, and a universal tool with battery power does not constitute an exception to this general rule. Website repair apartments in the home will tell you how to choose the screwdriver correctly and what is better to pay attention to. Share your opinion, leave feedback.

Therefore, the user needs to keep in mind that when choosing a universal tool, he consciously allows averaging of some characteristics, according to which the quality of the tool is evaluated, for example drilling speed or impact force. Moreover, some characteristics of the tool become simply incompatible, such as drilling with impact and drilling holes of small diameter. But the user enjoys all the advantages inherent in versatility, such as:

• Battery-powered tool provides autonomy from the household power supply
• Tool's multifunctionality provides ample opportunities for its use
• Simplicity and accuracy of operation

And this is far from an incomplete list of the possibilities of universal tools. At present, manufacturers offer a wide range of different models of cordless universal tools such as screwdrivers, grinders, planes and so on. In the present, there is a tendency to displace the familiar network tools with cordless tools, not only in everyday life, but also in production and industry. In the article, taking into account the urgency of the issue, the correct choice of the instrument, the characteristics and parameters of cordless screwdrivers are discussed in detail. Our choice is an online store of affordable prices. All the tools that work in many cities and showed credibility in the work.

Cordless universal tool - advantages and disadvantages

It is quite obvious that the optimal choice of the tool is primarily determined by the tasks that the instrument should provide, and, of course, the conditions of its future operation( operation in domestic conditions or the solution of professional tasks).A clear understanding of future operating conditions is all the more important given that the cost of multifunctional household tools is not much different from the cost of professional cordless screwdrivers. It is quite logical for the question to arise - how does a professional tool differ from domestic models. The main difference is that a professional screwdriver can withstand longer loads and less careful handling.

It is these parameters that distinguish the professional model from the simple, and therefore many manufacturers in the technical data sheets indicate that their product does not lose its performance after falling from a certain height. It must also be taken into account that even under repair conditions, a tool intended for domestic use is operated less intensively than in a production environment. However, such a high resource of strength and reliability is provided by functionality. It is for this reason that a professional tool is less functional than a household one.

For a clearer understanding of the subject, it is necessary to analyze the situation by considering a specific example. Suppose that in some furniture department a lot of QUATTRO universal cordless screwdrivers arrived, each of which is 4 screwdrivers in one Black & Decker KC2002FK brand.

If you look at it superficially, it seems that the furniture industry is equipped with excellent equipment produced by a well-known brand, and at the same time saved quite a decent amount of money( the cost of the set is 6000 rubles, while a separate tool is not much cheaper).But this judgment is superficial. Let's consider the question more thoroughly. In production, almost always for a working day you have to perform the same type of operations or to plan the tree, or to be engaged in the assembly of finished products, or to solve the questions of packing products. It is easy to guess that for performing these same functions only one tool is required( for example, a jig saw, a plane, a screwdriver, etc.).All becomes clear if you compare the characteristics of the screwdriver with the Black & Decker KC2002FK and the characteristics of a separate tool. Choose this universal cordless screwdriver for those who do not need to often apply individual components, and even this tool.

For greater clarity, it makes sense to review products of the same Black & Decker brand at a bargain price, namely the Black & Decker SC12K screwdriver, which costs 3.5 thousand rubles. In a screwdriver of the KC2002FK type, a 1.5 ampere / hour battery with a voltage of 14.4 V is used, while in a non-universal model a 1.5 ampere / hour battery with a voltage of 12 V is used, but its torque is 16 Nm, and for a more powerful universalScrewdriver only 10.5 Nm. The first significant sacrifice to ensure the universality of the device.

The universal tool can also be used as a jig saw, to which, of course, there is no point in presenting special requirements. The jigsaw of the same company KS999EK has a power of 600 W, and the adjustable blade speed varies from 0 to 3200 rpm.

The universal tool nozzle demonstrates the same travel frequency( 3000 rpm), but with its help it is possible to cut the material to a depth of up to 38 mm, and with a specialized jig saw the tree is cut to 65 mm.

Who better to choose this specimen? Universal screwdriver with Black & Decker nozzles KC2002FK is the ideal tool for home use, in which it is only used when necessary, that is, rarely. Using it in production makes no sense, and therefore in a professional environment, specialized tools equipped with the same type of battery packs, and performing strictly defined, standard functions, are widely used.

Overview of professional screwdrivers

A rational approach that allows to save money was demonstrated by BOSCH company that produced a model line of tools powered by the GSR 18 VE-2-LI Professional screwdriver battery. Note that the cost savings are very significant, given the high cost of a modern Li-Ion battery. Thus, buying an additional tool of this company, there is no need to purchase a battery.

How to choose the battery screwdriver correctly

After considering the basic properties of universal battery tools, we will discuss in more detail the choice of a cordless screwdriver, and consider the parameters that will allow using the tool not only at home, but also for commercial purposes.

Our review is limited to products equipped with NiCd brand batteries, which in the present are in great demand, since, despite all their advantages, Li-Ion batteries due to their high cost are not very popular. The main parameters to which you should pay attention when selecting a tool are:

• Tool set with 2 batteries with a voltage value of at least 12V
• Availability of a charger capable of restoring the model in 1 hour
• Tool rigidity in a large number of stages( tightening forces) with which the torque frequency is adjusted
• High torque value
• Cartridge type,which is equipped with the
• tool. The presence of several speeds of rotation

It is recommended to carefully read the warranty card, asome manufacturers do not provide a guarantee for the batteries. It is desirable, that the additional complete set included a set of nozzles, 3 storage batteries and a flashlight.

Armed with all the necessary knowledge, we will appreciate the advantages and disadvantages of the following models of well-known brands:

• Cordless screwdriver of the brand Makita 8281DWPE , whose price is 5.8 thousand rubles and equipped with a Li-Ion battery and blow option. Buy a screwdriver profitable.
• Accumulator screwdriver of the brand Hitachi DS12DVF3 equipped with flashlights, with a value of 3.6 thousand rubles
• Cordless screwdriver of the brand BOSCH GSR 12-2 Professional , whose price is 0t4 thousand rubles
• Cordless screwdriver METABO BSZ 14,4 Impuls, with a value of 7 thousand rubles and possessing a rather rare option "pulse"

Unfortunately in connection with the exchange rate, the value was not relevant and is an introduction

Of course, all selected for reviewing toolsOptions are of high quality, reliability and durability. Although all of the above-mentioned screwdrivers belong to the category of professional tools, at cost they are quite accessible to the average user, now we will better understand the characteristics and decide which one to choose better.

Cordless Screwdriver Makita 8281DWPE

The power source of the instrument is a new generation battery type Li-Ion with a voltage of 14.4 V, which is undoubtedly its advantage.

The tool comes with 2 batteries and a charger, which restores the device in just one hour. The speed of the screwdriver is divided into 2 ranges: the first speed range includes speeds from 0 to 400 rpm and the second range from 0 to 1300 rpm.

The screwdriver is equipped with a quick-action chuck( 10 mm), is equipped with 16 torque settings( maximum value of 36 Nm), and the weight of the tool is 1.7 kg. In addition to the typical operation, the tool is equipped with the strike option, and is able to perform from 0 to 18 thousand beats per minute.

has the following drawbacks:

• For a tool equipped with a shock function, the manufacturer supplied it with a rather weak cartridge
• Low battery capacity( only 1.3 Ah), which is not enough for intensive operation of the
• . There is a possibility that the hand can block the ventilation holeselectric motor during operation in the impact mode, and the ventilation holes are located so unsuccessfully that they will necessarily overlap in the case of wide laoney user
• gear housing screwdriver equipped with shock function, preferably made of a metal.

Accumulator screwdriver Hitachi DS12DVF3

The tool is made with a somewhat exotic exterior design. This design is not accidental. First, to forge the tool body is simply economically impractical, and, secondly, exotic patches protect the tool from falling. In addition, the pads also provide the necessary ergonomics for the screwdriver handle( the user's hand is protected from vibrations and does not sweat during heavy work).

Screwdriver includes a flashlight, a charger providing recovery of the product for 1 hour and a battery with a capacity of 1.4 Ah.

The screwdriver has 2 speed ranges: the first speed range includes speeds from 0 to 300 rpm and the second range from 0 to 1100 rpm.

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

Please note when selecting the main drawbacks of the tool:

• The morally obsolete, albeit highly reliable,
• drill chuck Failure to fix the replaceable bits on the bracket( the bit often clings to the clothes)
• The small size of the reverse button, although the layout itself is quite user-friendly. Buy this screwdriver for 4999 rub.here.

Cordless screwdriver BOSCH GSR 12-2 Professional

The tool is widely known in our country and externally executed in the style traditional for the company BOSCH.The product rotation speed range consists of 2 sub-ranges, namely:

• First sub-range from 0 to 400 rpm
• Second sub-range from 0 to 1200 rpm

The tool's technical equipment includes a quick-action chuck( 10 mm), the cover of the handle with a shock-absorbing coverand 25 stages of setting the torque, the maximum value of which is 27 Nm. The package includes 2 1.5 Ah batteries and a charger, which restores the workability of the product in 1 hour.

The main drawbacks of the screwdriver are:

• Absence of lining on the back of the
• tool Several unsuccessful location of the cartridge, which can cause inconvenience when replacing the replacement tool

Cordless screwdriver METABO BSZ 14,4 Impuls

The equipment is equipped with a rather rare "pulse" option that eliminatesthe need to use the core while drilling, and also allows the maximum use of torque, the value of which is 55 Nm. The speed range of the product consists of 2 subbands, namely:

• First sub range from 0 to 400 rpm
• Second sub range from 0 to 1400 rpm

The tool comes with a charger and 2 batteries.

The main drawbacks of the screwdriver are:

• Multiple size
• case Large size button for fixing the battery module, which can cause some inconvenience during operation.
• Unsuccessful location of the ventilation holes at the bottom of the tool that will quickly clog up in conditions of high dust concentration

After analyzing the meritsand the shortcomings of the models considered, we sum up our analysis in the final conclusions. The powerful METABO BSZ 14.4 Impuls, equipped with a useful "pulse" function, offers the user great opportunities, but its high cost and weight( 2 kg) clearly do not contribute to the popularity of the instrument. The possibilities of the screwdriver BOSCH GSR 12-2 Professional and Makita 8281DWPE are approximately the same. Note that the lower torque value of the BOSCH screwdriver is fully compensated by the capacity of the batteries and, consequently, by the longer running time. Maximum comfort during operation, apparently, is able to provide a screwdriver Hitachi DS12DVF3, despite its exotic design. Well-designed ergonomics of the instrument contributes to the emergence of a sense of reliability and confidence, and a flashlight and fixtures for attaching the model to the belt only increase the convenience of its use. The most important advantage of the model is its moderate cost, and this is with a high quality performance of the instrument. Disadvantages of all 3 models is the "memory" of NiCd batteries: you can charge batteries only when they are completely discharged. Now draw conclusions about how to choose the right screwdriver you know better than others, choose the appropriate option from the above written and do not forget about safety when working with the tool. Good luck in operation, and also leave your feedback!
