"A 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 application, secured by a chuck. Some powered drills also include a hammer function.
Drills vary widely in speed, power, and size. They are 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 versions are made for medicine, space, and miniature applications." - (en.wikipedia.org 01.03.2020)
