DRILL (c.35,000 B.C.E.)
Early humans learn how to bore small holes. It is thought that early man used a drill-perhaps a modified sphere-to pierce wood and animal skins. Muchlater the wood workers of ancient Egypt refined this technique by making any necessary with a bow drill. Adopted from the fire-stick,It had a cord wrapped round it and was held taut with a bow. Holding the drill vertically, the operator moved the bow backward and forward,pressing downward on alternate turns ,with an idle return stroke.The Romans replaced the bow drill with the auger,but the bit froze between turns,It was not untill the middle ages that use of the carpenter's brace made continuous rotation of the drill possible.
