<p>A tool holder (212) includes a socket (220) and a retaining mechanism (216) coupled to the socket (220) and operable in a retaining mode and a released mode. The socket includes a forward end with an opening (222) extending rearwardly from the forward end. The opening (222) also includes a non-circular cross-section. The retaining mechanism (216) is adapted to permit disposal of the bit (214) into an operative position within the opening (222) and to prevent axial movement of the bit mode. The retaining mechanism (216) is further adapted to permit axial displacement of the bit (214) out of its operative position when the retaining mechanism (216) is in its released mode. The retaining mechanism (216) includes a sleeve (260) coupled to the socket (220) for displacement toward the forward end of the socket (220) from a locked retaining mode into its released mode.</p> |
