ABSTRACT:
A tool holder for a machine tool is provided with a tool shank clamping mechanism in the form of an expanding or contracting sleeve, hydraulically actuated, and the chuck has an annular groove aft of an annular collar on the clamping mechanism. Circumferentially spaced conical screws, mounted axially in the collar, bear against the body of the tool chuck and allow fractional tilting of the clamping mechanism relative to the true holder and spindle axis to provide exact centering of the cutting end of the mounted tool.
