The Devolt screwdriver is quite common today among both private consumers and professionals. For any type of construction work, this tool is simply indispensable today. Among other things, it will be difficult, if not impossible, to assemble furniture without this equipment.
How to eliminate errors when choosing a screwdriver
If you decide to purchase a Devolt screwdriver, then you should pay attention not only to the cost of the unit. It is necessary to familiarize yourself with the information provided in the instrument passport. It will indicate technical characteristics that will help to understand what range of work can be performed using equipment.
Among them, one can single out the speed of rotation, torque, type of battery, if any. According to these parameters, it is worth making a choice in the direction of a specific model.
Professional or household option
The Devolt screwdriver can be household or designed to solve professional problems. If you do not use the tool often enough, removing it from the case twice a month, then there is no point in overpaying for a professional device. In this case, it is recommended to choose an amateur model that operates on battery power - it will be quite enough to solve domestic needs. Such a tool has all the necessary functions, has a small weight.
The Devolt screwdriver can be professional. With it, every day it will be possible to carry out a large amount of work. Such tools most often work from the network, have large sizes and weight. These units are chosen by those craftsmen who every day face the need to carry out construction and repair work.
Screwdriver speed and torque characteristics
The Devolt drill / driver may have different characteristics. For example, torque determines how much force the tool will exert on the screw being turned. This parameter determines the strength of the load resistance. If we are talking about solving everyday problems, then you should prefer a device whose torque varies from 10 to 15 Newton meters. As for professional models, their torque can reach 130 Newton meters. This allows you to drill very hard materials. For such units, the engine shaft in one minute makes from 1200 to 1300 revolutions. If you purchase a household model, you can count on 500 rpm. Depending on the torque, you will need to choose the length of the screw to be screwed 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, eliminating the possibility of breakdowns. The Devolt-DSD 710 D2 screwdriver differs from alternative tools in that the master can adjust its torque independently. For this, a stop is used, which is a ring located after the chuck. With it, you can set a certain position, and the screw will stop screwing. This function allows you to protect the tool from disruption of the slot from the self-tapping screw, wear of the bit and deep sinking of the elements to the surface.
Extra features
Impact screwdriver "Devolt" has a ratchet, which is located inside the engine. It protects against overload by allowing the rotating shaft to slip. If you set the maximum torque, then this will be enough to unscrew the very tight screw and not overload the engine. In order to put the tool into drilling mode, it is necessary to install the coupling in the extreme opposite position. The torque limit will be removed in this case, and the tool will work 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 speed. The master must take care of the quality of the power supply, it must have the ability to hold a charge. And with a dead battery, the power of the device should be maintained.
