The devices of the first type have high power, a large number of functions and a resource of work. Their torque can reach 130 Nm, which makes it possible to make holes even in solid materials. In household models, this indicator is usually 15-20 Nm. On the other hand, a household screwdriver will be enough for housework.

What else to consider

The next important indicator is the power source. The modern market offers cordless screwdrivers and network-powered devices. Models of the first type are not tied to the presence of electricity and wires. Batteries are nickel-cadmium, lithium-ion and other types. Lithium-ion products are environmentally friendly, but at very low or high temperatures they stop working. Nickel-cadmium analogues can withstand 1000 charges, but cadmium is toxic and can be harmful to human health.
