Electric screwdriver is a common power tool used to screw fixing and removal. It is also called power screwdriver or motorized screwdriver. Electric screwdriver is an ideal tool for electronic equipment or industrial, commercial, and medical equipment manufacturing that require complex operations. Its compact size is easy to store and carry, can control torque and increase productivity. When the preset torque is reached, electric screwdriver will automatically stop, thus simplifying the operation.
The head of electric screwdriver is equipped with a bit holder, which can be magnetic or have a quick release system. The bit holder allows you to quickly insert the bit corresponding to screw head. The main difference between electric screwdriver and electric drill is that the electric screwdriver is only used for screwing, and electric drill can be used for screwing and drilling.
Types of Electric Screwdrivers
There are two basic types of electric screwdrivers: standard and brushless.
The standard electric screwdriver has a small carbon brush inside, the brush is used to conduct electricity between stator wire and rotor wire. Although brushed screwdrivers are effective and accurate, as the use time increases, carbon brush heating will shorten the life of electric screwdriver. Compared to a brushless electric screwdriver, a standard electric screwdriver usually requires more frequent maintenance. The frequency of maintenance depends on the number of screws it tightens every day.
Obviously, a brushless electric screwdriver is a screwdriver that does not contain carbon brushes. Because brushless power tools generate less heat, they have less wear and longer service life. If you want to use an electric screwdriver for long-term and large-scale work, a brushless electric screwdriver is the best choice.
