Black & Decker is a popular manufacturer of corded and cordless power drills. These drills come with either a keyed or a keyless chuck to hold the bits securely while drilling. A keyed chuck has gears around the perimeter of the chuck, and a matching geared key is inserted into a hole on the side of the chuck to loosen or tighten the chuck. Conversely, a keyless chuck is loosened or tightened by holding the chuck securely. If the drill chuck becomes damaged, the chuck can be replaced in moments with some basic hand tools.
