Abstract
A chuck 30,232 includes a pair of jaws 178,304,306 which are located within an axial opening 114,246 of a body 106,234 for receipt of a shank of a bit therein. A roller 186,238 is located in a slot 134,272 of the body 106,234 and can be pressed into the shank of the bit to clamp the shank between the jaws 178,304,306 and the roller. A sleeve 196,240 is biased and structured to normally urge the roller 186,238 into the shank-pressing position, and is movable relative to the body 106,234 to facilitate removal of the shank from the chuck 30,232.
