摘要：
A tool-bit holder (10) for varying tool-bit shank profiles comprising a hub (12) having a longitudinal bore (28) adapted for receiving a tool-bit shank (66, 70, 80). The hub (12) has a plurality of radial slots (38) communicating with the first section (30) of the longitudinal bore (28). The tool-bit holder (10) has a collar (14) fixedly attached to the hub (12) adjacent the open (29) and disposed annularly about the hub (12). A sleeve (16) is axially slidably mounted and disposed annularly about the hub (12). The sleeve (16) has a plurality of radial bores (48), each being in communication with a respective radial slot (38) of the hub (12) with a detent ball (18) disposed within each. A spring (20) is provided for biasing the sleeve (16) towards the open end (29) wherein the detent ball (18) engages an inner ramp face (46) of the collar (14).
