Where and for what use a screwdriver

Such a tool as a screwdriver is an indispensable thing in any economy. It is used in repair work, in construction, it is indispensable in solving many household issues (furniture assembly, fastening eaves, shelves, cabinets, etc.). The main functions of the screwdriver are to screw in and out any fasteners and their parts. Also with the help of it you can drill a wooden, metal surface or cut threads. To date, the market of power tools is quite large and diverse, so it is not surprising that more and more buyers are asking the main question: what kind of screwdriver is better to buy?

Depending on the characteristics and purpose, the screwdrivers can be divided into mains or accumulators designed for professional activity or home use.

Like any other tools, screwdrivers are divided into professional and household. However, not all the characteristics that a professional tool possesses will be in demand in everyday use. But the price may differ significantly in favor of household models. For example, for tightening screws, nuts and screws, a torque of 15 Nm is quite enough, while professional models are produced with a mark of 130 Nm. If you need to drill a fairly hard surface – household tools will not be enough.

The next thing you need to pay attention to is the motor shaft. The number of revolutions of prof. tool 1200-1300 revolutions per minute, while household options are capable of only 400-500. And of course, it is important how often you plan to use a screwdriver. Powerful professional models are suitable for frequent use and large amounts of work. If in the plans the use of a screwdriver is not more than 1 time in 2 months – you can safely choose the affordable amateur quality options available.

Another difference that divides screwdrivers into two basic types is the principle of power: mains or battery. The first ones are quite heavy, and they can work only with access to the power grid. This makes it impossible to use them in the construction and repair of those facilities to which electricity has not yet been supplied. The presence of the power cord delivers a lot of inconvenience in the process of use, especially when it comes to work at height. Such a tool is less mobile.

Cordless screwdrivers are much easier, they are autonomous and allow you to work with them in almost any conditions. Let’s try to figure out how to choose a cordless screwdriver?

The main advantage of this type of battery is the lowest price compared to other types of batteries. They easily tolerate cold, which allows you to work with them at fairly low temperatures, and can withstand up to 1000 recharges.

The main disadvantage is the content of toxic and allergenic substances – cadmium. Nickel-cadmium batteries have a low memory effect, that is, they reduce capacity after each charge. It can not be fed until the previous charge is fully used.

The main disadvantage in the use of non-wired power tools is the wear of the charger. The main reason for the failure is that the banks for the battery of the screwdriver fail. In this case, it is necessary to disassemble the battery and detect the broken jar using a voltmeter. Then you can assemble the device without a failed jar, or replace it with a new one.

Another common cause of tool failure is breakage bits for the screwdriver. Which is better, more practical and durable – depends on many factors. The main one is the material from which the nozzles are made. The strongest is steel R7 – R12 with titanium-nitride or chrome-vanadium coating. Also on the wear resistance affects the way of processing bits. The most common are milling or forging.
