摘要：
A tool-bit holder has a hub, wherein the hub has a longitudinally extending axial bore for receiving a tool-bit therein, a detent ball radially projecting into the bore to selectively engage the tool-bit, and a circumferential ramp that is longitudinally moveable over the detent ball to cause radial movement thereof. A longitudinally moveable member extends through a slot in the hub and radially into the bore. The circumferential ramp is moveable as a function of longitudinal movement of the moveable member relative to the hub.
