The cordless drill’s top use involves attaching and assembling. Using a screw bit, the craftsman can position a screw on the end of the bit and quickly insert it into the project. With the flip of a switch, the cordless drill driver can rotate counterclockwise, making it invaluable for removing screws as well as installing them.
Pilot holes: When you’re inserting screws into wood that may split, a cordless drill, with a bit one size smaller than the diameter of your screw, lets you drill a pilot hole before inserting the screw. This is beneficial in finish carpentry where even a small split would detract from the quality of the item. Because a screw digs into the wood and separates the grain, it has a tendency to split the wood, especially if the screw is large.
