Abstract

The chuck has an externally toothed crown wheel (24) which is rotated via a key to effect relative displace-of the jaws (16) and the chuck body (10). A hollow cylindrical cap (34) rear crown wheel extension is socketed (32) to receive a two-piece union bolt (30) connecting the chuck to the drill spindle, a ball bearing (38) locating inside the cap, between seats (40) on the opposed faces of the chuck body (10) and the union bolt socket (32), and serving to promote an automatic axial alignment of the union bolt with the drill bit engaged by the chuck jaws. The jaws (16) slide in axially divergent apertures (14) in the chuck body (10) and have threads (22) cut on their outer faces, with an inwardly projecting and internally threaded ring (20) engaging jaw threads and being movable by the crown wheel to effect jaw displacement.
