Drill Chucks & Accessories
Drill chucks and accessories are used to install and remove drill bits from a drilling machine, milling machine, or lathe. Drill chucks secure drill bits or other cutting tools to a machine spindle. Drill chuck keys tighten or loosen the jaws on keyed drill chucks so that drill bits can be inserted or removed from the chucks. Chuck key holders attach chuck keys to a drill to prevent them from getting lost.
