Abstract
Abstract A tool holder includes a shank adapted at one end to hold a tool and to be clamped in a machine tool at its other end. The shank has a portion that provides accurate radial location, and also has means which are adjustable in order to provide accurate axial location. Such axially adjustable locating means include an elongated ramp accompanied by means defining a flat surface encircled by a lock ring which can engage the adjacent end surface of a portion of the machine tool which holds the tool holder. Any force tending to push the tool holder further into the machine tool is resisted by the inability of the lock ring to move up to a higher portion of the ramp. Preferably, there are a plurality of aligned ramps.
