Screwdriver performance in speed and torque

Drill-screwdriver "Devolt" can have different characteristics. For example, the torque determines the force with which the tool will act on the screw to be screwed. This parameter determines the strength of the load resistance. If it is a question of solving everyday problems, then it is better to prefer a device whose torque varies from 10 to 15 Newton meters. As for professional models, their torque can reach a rate of 130 Newton-meters. This allows you to drill very hard materials. At such units, the motor shaft makes from 1200 to 1300 revolutions per minute. If you purchase a household model, you can count on 500 rpm. Depending on the torque, you will have to choose the length of the screw and its diameter. With the use of more powerful screwdrivers, it is possible to twist long and thicker elements.

Among other things, these devices can be used when working with solid materials, excluding the possibility of breakdowns. The screwdriver "Devolt-DSD 710 D2" differs from alternative tools in that its torque can be adjusted by the master independently. For this, a limiter is used, which is a ring located after the chuck. With its help you can set a certain position, and the screw will stop screwing. This function will save the tool from splitting of the slot in the self-tapping screw, wear of the bit and deep weaning of the elements in the surface.

Additional features

Impact screwdriver "Devolt" has a ratchet, which is located inside the engine. It protects against overloads, allowing the rotating shaft to slip. If you set the maximum torque, this will be enough to turn out the tightest screw and do not overload the engine. In order to put the tool into drilling mode, it is necessary to install the clutch in the extreme opposite position. The torque limit will then be removed, and the tool will operate on the principle of a conventional drill.

The cordless screwdriver "Devolt" must be selected correctly, while it is necessary to check the stability of its operation under certain loads, as well as the safety of the rotational speed. The master must take care of what the quality of the power supply is, it must be able to hold the charge. And when the battery is worn out, the power of the device must be maintained.
