  • Adjustable nosepiece for a drill motor
    Patent number: 4538943
    Abstract: A nosepiece for a drill motor. The nosepiece is adjustable to allow the nosepiece length to be changed rapidly to compensate for different drill lengths. The nosepiece is threaded to mate with threads on the drill motor housing and can be adjusted longitudinally along the motor center line axis. When the nosepiece is threaded along the housing to a desired location it is locked in place by a locking ring keyed to the nosepiece and fixed in position on the drill motor housing by a hand adjustable set screw.
