<p>A quick-change tool holder (10) includes a tool support member (12) which is adapted to be mounted on a lathe turret or mounting block of a machine, a cutting head (14) formed with a seat (36) for receiving a cutting tool (38), and a clamping mechanism (16) for clamping the cutting head (14) to the support member (12). The tool support member (12) includes an axial bore (28) which receives a tubular shank (32) of the cutting unit (14). The clamping mechanism (16) is disposed within the axial bore (28) and includes a pair of radially expandable locking elements (94) to engage the tubular shank (32) of the cutting unit (14). The clamping mechanism (16) includes a key (82) which engages with a corresponding keyway (48) on the tubular shank (32) for angularly locating the cutting unit (14). Means are provided for rotating the clamping means (16) about a longitudinal axis of the support member (12) to change the angular location of the cutting unit (14).</p> |
