In order for the screwdriver to serve for a long time and be practical in use, it is necessary to choose the right model of the tool. Many users make mistakes when buying. Let's see exactly what mistakes are most often made.

Incorrect battery selection

The battery is the most expensive item. In order not to charge the battery after every hour of operation, it is recommended to pay attention to the following battery criteria:

  • voltage, which determines the power of the unit;
  • capacity (has a direct impact on the duration of the battery without recharging);
  • the presence of a memory effect (it is better if it is absent).

Several varieties of batteries are known. Among them, the most practical and effective are lithium-ion batteries. They have a high level of power and capacity. At low temperatures, such batteries do not discharge. They do not have a memory effect and are not subject to self-discharge.

You can find out precisely these and other criteria of the batteries of a certain model from the technical data sheet of the tool.

Buying a single-speed screwdriver for drilling and screwing

The screwdriver is a universal tool: in addition to drilling holes, it is used to screw fasteners. To buy a single-speed unit for this purpose is a mistake. In order for the screwdriver to be able to perform all the functions assigned to it, it is recommended to purchase a tool whose design is equipped with a speed controller. This is due to the fact that drilling and screwing operations are performed at different speed modes. In addition, it is also necessary to work with different materials at different speeds.

The most powerful is not always the best

When buying a screwdriver, criterion such as power is of no small importance. Do not choose models with maximum power. The choice of power level depends on the type of work and the frequency of its implementation.

If the unit is supposed to be used to perform simple operations in everyday life, it is better to give preference to models with low power. In this case, the purchase of screwdrivers with a high power indicator will be inappropriate.

It should also be borne in mind that a powerful screwdriver has large dimensions and weight, which puts a lot of stress on the hands of the master during work.

Buy an impact driver instead of a hammer drill

Many modern screwdriver models have wide functionality, including the beating mode. This does not mean that a screwdriver can be used as a hammer drill. Such a function in the tool is designed to more efficiently and quickly screw in fasteners or drill holes in the work surface.

If the model of equipment with the function of a punch is used to beat walls, it will quickly fail and you will have to buy a new one.

Wrong packaging choice

Complete with a screwdriver is a second battery, a set of drills and bits. If you buy a screwdriver in cardboard packaging, it will not be very convenient to store all the components in it. In addition, this type of packaging does not have a long shelf life.

Masters recommend giving preference to packaging in the form of a plastic case with a pen. In it, the tool will be convenient not only to store, but also to transport.

If you do not make the above mistakes when buying a screwdriver, the purchase will be profitable. The tool will last a long time, and its use will be practical.
