1. A power tool chuck comprising: at least one claw portion including an inner surface generally parallel to a centerline of the chuck and movable from a first position spaced apart from the centerline toward a second position located closer to the centerline; a collar configured to move such that as the collar moves from a third position to a fourth position, the at least one claw portion is forced from the first position toward the second position such that the inner surface is forced against a shank positioned within the chuck; a locking member movable between a fifth position whereat the locking member locks the collar in the third position and a sixth position whereat the locking member does not lock the collar in the third position; a button axially aligned with the centerline and movable between a seventh position whereat the locking member is forced into the fifth position and an eighth position whereat the locking member is free to move into the sixth position; and a ball holder movable between a ninth location whereat the ball holder impedes movement of the locking member from the sixth position toward the fifth position and a tenth location whereat the ball holder does not impede movement of the locking member from the sixth position toward the fifth position, wherein the at least one claw portion is configured to clamp the shank toward the centerline via pressure applied by the inner surface to a surface of the shank that is substantially parallel to the inner surface.
