Corded power screwdrivers are used in production and maintenance tasks to install and remove screws with greater speed than manual screwdrivers and greater precision than drills. They have a chuck that holds interchangeable screwdriver bits and a motor that rotates the bits to turn screws without overdriving them, snapping them, or stripping the screw head. These screwdrivers plug into an outlet to allow longer run times than cordless screwdrivers for applications where portability isn't a concern. They maintain full power during operation and don't have batteries that require recharging.
