ABSTRACT:
A drill chuck according to this invention has a chuck body centered on and normally rotatable about a chuck axis and formed centered on the axis with a plurality of angled guide passages each having an axially forwardly open front end and an axially rearwardly and radially outwardly open rear end, respective jaws displaceable in the guides, projecting from the front ends thereof, and formed with teeth exposed at the respective guide-passage rear ends, and an adjustment sleeve axially fixed on the body and rotatable thereon and formed with an internal screwthread meshing with the teeth of the jaws so that rotation of the sleeve in one direction advances the jaws and opposite rotation retracts them. A grip ring on the chuck body centered on the axis axially forward of the adjustment sleeve has an exposed outer surface provided with grip-enhancing formations. Formations on the body and on the grip ring axially and rotationally fix the grip ring on the chuck body.
