ABSTRACT:
A drill chuck has a body centered on and rotatable about an axis, a plurality of jaws radially displaceable on the body, an adjustment sleeve rotatable but not axially displaceable on the body and engaging the jaws for radially displacing same, and a locking ring rotatable on the body at most through a small acute angle and axially displaceable on the body between a freeing position and a locking position. The locking ring and adjustment sleeve are formed with axially interengageable teeth that are meshed in the locking position of the locking ring and that are out of engagement with each other in the freeing position of the locking ring. An actuating ring is rotatable but not axially displaceable on the body adjacent the locking ring. Angled formations between the rings couple same together for axial movement of the locking ring into its freeing position on rotation of the actuating ring in one rotational sense and for opposite axial movement of the locking ring into its locking position on rotation of the actuating ring in the opposite rotational sense.
