摘要：: <p>A mount for the mounting of milling tool bits in a recess of a tool bit holder. A screw extends through a bore of the bit and screws into a threaded hole of the holder. A longitudinally slit sleeve is arranged between the screw and the inner wall of the bore of the bit and encompasses the screw. The end of the sleeve opposite the head of the screw rests upon a shoulder of the holder in such manner that when the screw is tightened the screw forces the sleeve into rotation about a rotary axis defined by the point(s) of contact of the sleeve with the shoulder. This rotary axis extends transverse to the screw axis such that an upper end of the sleeve is forced into engagement with the inner wall of the bit bore to secure the bit radially and axially. Replacement or indexing of the bit is permitted in response to minimal unscrewing of the screw, e.g., 90 DEG to 180 DEG .</p>
