<p>A quick-change tool holder (10) includes a center-height adjustment mechanism for adjusting the center height of the cutting tool. The holder includes a tool support (12) to be mounted on a lathe turret or mounting block of the machine, a cutting head (14) formed with a seat for a cutting tool, and a mechanism (16) for clamping the cutting head to the support. The support includes an axial bore (28) receiving a tubular shank (32) of the cutting head. The clamping mechanism is in the bore and includes a pair of radially expandable locking elements (94) engaging the cutting head shank, and a key (82) engaging a keyway (48) in the shank. Rotation of the clamping mechanism changes the orientation of the cutting head to in turn determine the center height of the cutting tool.</p> |
