Although initially intended to aid the handymen to go about their crafts a lot faster, traditional screwdrivers have ceased to be the top of the screwdriver product range. The new kid on the block is the electric screwdriver. These electric devices are self-powered and self-rotating. Instead of the hand generating the desired torque (the manual twisting motion) to loosen or tighten a screw, this new screwdriver sports a simpler solution; a control button.
This button activates the screw to naturally drive the screw into or out of the hole. They contain a gear for controlling the motor speed, an electrical battery or power cord for energy supply and an electric motor to generate the torque.
