Patent abstract
A drill chuck with an impacting structure that may be selectively employed to drive the jaws of the chuck into further engagement with or out of engagement with a bit. The chuck is configured so as to be capable of generating relatively high torques in a loosening direction so as to ensure that the bit can be removed from the jaws of the chuck.
