Electric drill

An electric drill is a drill which is driven by an electric motor. The invention of the electric drill is credited to Arthur James Arnot and William Blanch Brain of Melbourne, Australia who patented the electric drill in 1889.[1] In 1895, the first portable handheld drill was created by brothers Wilhelm & Carl Fein of Stuttgart, Germany. In 1917 the first trigger-switch, pistol-grip portable drill was patented by Black & Decker.[2]
