Abstract
A chuck includes a pair of jaws which are located within an axial opening of a body for receipt of a shank of a bit therein. A roller is located in a slot of the body and can be pressed into the shank of the bit to clamp the shank between the jaws and the roller. A sleeve is biased and structured to normally urge the roller into the shank-pressing position, and is movable relative to the body to facilitate removal of the shank from the chuck
