ABSTRACT:
An indexing coupling for a drill includes a hollow inner race, a hollow outer race, and a sleeve member. The hollow inner race and hollow outer race are affixed to one another by a plurality of ball members which are positioned by a plurality of detents in the hollow inner race. The balls also extend into holes in the hollow outer race. When the balls are positioned within the holes in the hollow outer race and within the detents in the hollow inner race by the sleeve member, the hollow inner race and the hollow outer race are rigidly connected one with respect to the other. When the sleeve member is moved the ball members become disengaged from the hollow inner race thus allowing indexing of the outer race with respect to the hollow inner race. This indexing of the hollow outer race with respect to the hollow inner race allows selective rotatable indexing of the drill housing with respect to the nose piece.
