What is a Power Drill?

Power drills are handy tools for numerous jobs around the home, from installing large picture hangers to making furniture.

A power drill is an electrical motor that rotates a replaceable drill bit to make a hole in wood, plastic, or metal. Alternately, a screwdriver tip can be installed to turn screws. The parts of a power drill include the handle, an on/off trigger with safety latch, a reversing switch for changing the rotation direction of the drill bit, a torque adjustment, and the chuck that holds the drill bit in place. Corded drills are powered by a 110-volt electrical cord inserted into an electrical receptacle; cordless drills are powered by a battery in the drill’s handle.
