ABSTRACT:
A chuck has a chuck body having an outer surface and formed with a forwardly open hole defining an axis and normally receiving a drill bit, a plurality of angularly generally equispaced guide bores extending at an acute angle to the axis and having inner front ends opening in the hole and outer rear ends opening on the outer surface, and respective chip-shedding passages opening radially inward into the guide bores and radially outward on the outer surface. Respective jaws displaceable in the guide bores have front ends engageable with a bit in the hole and radially outwardly directed teeth. An adjustment ring engaged around the body fits with the teeth of the jaws so that rotation of the ring in one direction advances the jaws in the body and rotation in the opposite direction retracts the jaws for respectively clamping and unclamping the drill bit in the hole.
