ABSTRACT:
A drill chuck has a chuck body defining a chuck axis and provided with a plurality of generally angularly equispaced and radially displaceable tool-engaging jaws. A tightening ring and sleeve rotatable on the chuck body about the chuck axis have formations that radially displace the jaws to grip a tool. An eccentric is rotatable on the chuck body about an eccentric axis radial of the chuck axis. This eccentric has an eccentric surface spaced from the ring and engageable via a locking member axially on the tightening ring to lock this ring in the chuck body. This eccentric is rotated about the eccentric axis by insertion of a non-cylindrical tip of the standard chuck-tightening key into a correspondingly shaped recess of the eccentric.
