Abstract
A chuck including a chuck body that supports a plurality of jaws. An outer sleeve is axially fixed with respect to the chuck body. A nut is coupled to the outer sleeve, and the nut is movable axially and radially relative to the chuck body. The nut interacts with the jaws such that when the outer sleeve rotates, the nut moves axially and radially relative to the body.
