A Hand power drill is a tool primarily used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver, depending on the application, secured by a chuck. Some of the hand-powered drills also include a hammer function.
Drills vary widely in speed, power, and size. They have characteristically corded electrically driven devices, with hand-operated types dramatically decreasing in popularity and cordless battery powered ones proliferating.
Drills are commonly used in woodworking, metalworking, machine tool fabrication, construction and utility projects. Specially designed drill versions are made for medicine, space, and miniature applications
