ABSTRACT:
A drill chuck has a chuck body rotatable about a chuck axis and having a rear end adapted to fit with a drive spindle and a front end formed with a tool recess. A plurality of jaws angularly spaced on the body about the axis and exposed in the tool recess are radially displaceable relative to the body between inner and outer positions. A tightening ring is axially fixed but rotatable about the axis on the body. Screwthread formations between the tightening ring and the jaws can move the jaws radially together and radially apart. A tightening sleeve surrounding the body and connected to the tightening ring is adapted to be gripped by hand to rotate the ring in the directions. A shield sleeve surrounds the body between the tightening sleeve and the body front end and is supported on the body for rotation thereon about the axis independently of the body and of the tightening sleeve.
