ABSTRACT:
Disclosed is a quick-change nosepiece (10) for a power drill (27) capable of telescoping by very small increments in the longitudinal direction, of angular or rotational displacement, and of quick and easy engagement and disengagement so as to provide access to the drill bit (29). Alternatively, a nosepiece (10) may be changed with one of greater or lesser length to correspond to the length of the drill bit (29) as the bit is changed.
