A tool fastening mechanism has a housing , in which a clamping opening is embodied for receiving a tapering tool shaft clamping end of a tool part . The clamping opening tapers inward in the introduction direction of the clamping end of a tool part , and furthermore the tapering sides are inclined toward one another in a plane extending perpendicular to the introduction direction, as a result of which the opening has a trapezoidal cross section, and the length of this cross section decreases away from the orifice of the clamping opening . The housing furthermore has a transverse opening , which intersects the clamping opening and in which a locking pin is received. Upon introduction of a tool into the fastening mechanism, a tapering edge of the pin comes into engagement with a front edge of an oblong hole , embodied in the clamping edge of the tool part , and the resultant engagement action draws the clamping end deeper into the clamping opening , while the pin is driven farther into the transverse opening . The combination of the double tapering of the clamping opening and the longitudinal locking accomplished by the locking pin makes it possible to effectively restrict all six degrees of freedom of the tool part, within the production tolerances attainable by conventional mass-production methods.
