ABSTRACT:
A chuck has a chuck body adapted to be rotated about an axis and formed with an axial passage having a seat on which three jaws are slidable to grasp a tool shank. A tightening ring is formed on its inner periphery with threads that engage threads on the jaws to displace them axially. A cylindrical sleeve has one end resting on an outside ledge formed on the ring and is deformed at this one end into a groove on the ring which has a sharp edge that bites into the sleeve.
