How to Replace Electric Drill Motors

Electric drills are a convenient tool for making home repairs and improvements. With a variety of attachments available, you can use a drill to make holes, remove paint or rust and even to pump water. The motor inside the drill converts electrical energy into rotational force to drive the attachments. Over time, the motor can wear out or suffer damage from misuse. Replacement motors are available and are easily installed using a screwdriver.
