Abstract
Attachments for self-locking or conventional key-operated chucks on hand drills make possible simplified operation thereof. An externally threaded ring carried by the drill surrounding the chuck is internally beveled at its outer end and mates with a threaded nut. A split ring with wedge-shaped cross section is positioned between the nut and the beveled end of the ring so as to clamp the chuck to the ring when the nut is tightened. A cap made of an elastomer attached over the nose of the chuck has in its end a slot or crossed slots which grip a drill bit when it is thrust therethrough.
