How to choose the right cordless screwdriver.

Almost the majority of construction tools users prefer to have only a versatile tool. The reasons for this are quite natural desire: rational to have one tool in the economy, which can replace several. in closet savings and on the shelves of the obvious. However, all things exist as its advantages, and disadvantages, and versatile tool with battery is no exception to this general rule. Site repair of an apartment on their own tell how to choose the correct screwdriver and it is better to pay attention. Share your opinion and, leave feedback.

Therefore, the user should keep in mind, that choosing a universal tool, he consciously admits averaging some characteristics, according to which the estimated quality of the instrument, such as the drilling rate or impact force. Moreover, some characteristics of the instrument are simply incompatible, such as hammer drilling and drilling small diameter holes. Instead, the user enjoys all the benefits inherent flexibility as that:

  • Tool with battery provides a battery life of household electric
  • Multifunctional tool provides wide possibilities of its application
  • The simplicity and accuracy

And this is a partial list of features of the universal instruments. Currently, manufacturers offer a wide range of different models of cordless tools such as universal: Screwdrivers, sanders, planes, etc.. This trend displacement familiar networking tools cordless tools, not only in everyday life, but also in the generation and industry. article, given the urgency of the matter, The right tools, examines in detail the characteristics and parameters of cordless screwdrivers.

Cordless Tools - advantages and disadvantages

Absolutely obvious, that the optimum tool selection is primarily determined by the tasks, the solution of which the tool should provide, and, of course, the conditions of its future operation (Operation in a residential or professional applications). A clear understanding of the future operating conditions is even more important, if consider, that the cost of multi-functional household tools is not much different from the cost of professional cordless screwdrivers. Quite logically the question arises - what distinguishes a professional tool from household models. The main difference is manifested in, that professional screwdriver can withstand longer load and less careful handling.

It is these parameters and distinguish professional from a simple model, and so many manufacturers specify data sheets, that their product does not lose its efficiency after a fall from a certain height. It is also necessary to take into account, that even in the repair tool, intended for domestic use, operated less intensively, than in a production environment. However, such a high strength and reliability of the resource provided by the functionality. It is for this reason, a professional tool less functional, than home.

For a more clear understanding of the subject matter, you need to analyze the situation, The concrete examples. supposing, that in some furniture shop received a batch of universal cordless screwdrivers brand QUATTRO, each of which represents a 4 screwdrivers in one brand Black&Decker KC2002FK.

On the surface,, it seems, that furniture manufacture equipped with excellent technique, produced by well-known brand, and thus to save quite a decent amount of money (set the price 6000 g., whereas the standalone tool does not cost much cheaper). But this judgment is rather superficial. Let us consider the question thoroughly. On the production is almost always for the time necessary to perform the same operation, or wood rasp, or to engage in the installation of the finished product, or address the issues of packaging products. Not hard to guess, that only one tool is required to perform the same type of functions (eg, fretsaw, plane, screwdriver, etc.). All will become clear, if we compare the characteristics of the screwdriver with nozzles Black&Decker KC2002FK and features a separate tool. Choose this versatile cordless screwdriver those, who do not need so often to apply the individual components, and even the tool itself.

For greater clarity, it makes sense to consider all products of the same brand, namely screwdriver Black&Decker CР12K, which is the cost of 3.5 thousand. rubles. Screwdriving KC2002FK type used battery capacity 1.5 Ampere / hour and voltage 14.4 AT, while in no universal model used battery capacity 1.5 Ampere / hour and voltage 12 AT, but the value of its torque is 16 nm, while the more powerful universal screwdriver all 10.5 nm. The first significant sacrifice to ensure versatility of the device.

Versatile tool can also be used as a jigsaw, to which, of course, There are specific requirements does not make sense. Jig of the same firm has a capacity KS999EK 600 W, and adjustable frequency varies from blade moves 0 to 3200 stroke / min.

Nozzle universal device demonstrates the same stroke frequency (3000 stroke / min), but it can help to cut the material to a depth of 38 mm, and specialized jigsaw to cut a tree 65 mm.

Who better to select this instance? Universal screwdriver with nozzles Black&Decker KC2002FK is an ideal tool for use in the home, in which it is used only when necessary, that is quite rare. Its use in the production of meaningless, and so in a professional environment are widely used specialized tools, equipped with the same type of battery packs, and for a strictly limited, standard features.
