A drill chuck with key is a device used to secure drill bits into power drills and other rotary tools. It features three jaws that grip the drill bit shank when tightened with a separate key. The key is inserted into a slot on the chuck and rotated to expand or contract the jaws, allowing for secure clamping of the drill bit.
