If you are an amateur tinker, you probably have in your arsenal a screwdriver, the price and quality of which you are comfortable with. If not, then you are one of those who are only going to make a profitable acquisition. Without this tool will not do when repairing or during construction. For the solution of any household tasks, such equipment is suitable. However, it is initially necessary to determine the main selection criteria, which will be discussed below. Some consumers, before buying a particular product, carefully study the reviews, because they sometimes make the right purchase. If the choice is made correctly, the spare parts for the screwdriver will not be needed for the entire service life.

Selecting a model by speed and torque

It is important to study the rating before visiting the store. Screwdrivers can be selected on the basis of reviews of experienced masters. Experts advise to consider the speed and torque. The last parameter will determine what force the tool applies when fastening the fasteners. This characteristic also indicates the strength with which the equipment resists the load.

If you want to choose a tool for solving household tasks, then the torque should vary between 10 and 15 Newton meters. Professionals choose equipment with a torque limited to 135 Newton meters. As a result, the masters get the opportunity to work with solid materials. The motor shaft of such a device will be able to make 1300 revolutions per minute.

If we are talking about household models, we will have to be content with 500 rpm. It is important to consider the rating before visiting the store. Screwdriver, chosen by you based on the recommendations of consumers, will meet all the requirements. Depending on the torque, you should also choose the length of the fasteners, as well as its diameter. If you compare the screwdriver with other electrical tools, you should highlight the possibility of adjusting the torque, for which the limiter is used. This addition is represented by a ring located after the chuck. Once the master has overcome the effort, after which the screw no longer enters the wall, he will hear the characteristic sound of the rattle. Such a limitation will save the tool from splitting the slot, worn bits and deep drowning fasteners in the surface.

Choice of model depending on the power source

When to choose a screwdriver with a nickel-metal hydride battery

A screwdriver can be powered from a Ni-MH battery. They are becoming more common in recent times, as European models are equipped with them. They are ecologically friendly, light in weight and small in size. Spare parts for the screwdriver can be purchased at the service workshop, as well as the battery.

That is why, for Russian conditions, they fit perfectly well. But these batteries are characterized by a strong self-discharge and a memory effect, which can be called significant drawbacks.

When to choose a lithium-ion battery

For example, lithium-ion batteries are installed in screwdrivers not so often. They are characterized by maximum sensitivity to cold, and their power is low. The master can count on 3000 recharges, the memory effect of such a battery is missing. Do not be surprised that the equipment will have a high cost, which is not compensated even by impressive capacity. Self-discharge, these batteries are almost not affected, which is why it is convenient to use them at home, when you often need to use the instrument.
