Who Invented the Drill
The earliest drills date back to the Harappans and Egyptians. Obviously, these drill were not electric! The Harappans and Egyptians used bow drills for both woodworking and dentistry. They were carved so that one end would have minimum friction and the other end maximum friction when turned. With enough pressure and speed, the dust would ignite and drilling would be achieved. The first electric drill is credited as being invented by Arthur James Arnot in 1889. The first portable electric drill was invented by William Fein six year later, in 1895.
