摘要： A cutting tool assembly includes a cutting head having a coupling face provided with a multilateral recess, a shank having a coupling face provided with a multilateral recess corresponding to that of the cutting head, and a multilateral coupling plate which fits complementarily into the interior space created by the multilateral recesses. The cutting tool assembly provides a more stable coupling structure, since rotational torque is transmitted through the multilateral coupling plate from the shank to the cutting head, whereas in the prior art coupling screws are used to directly bear the torque force.

摘要： An assembly includes a double-sided indexable cutting insert and a reinforcing part. The assembly can be used to process metallic materials and the like. The polygonal, double-sided indexable cutting insert of the present invention has a plurality of convex portions at each corner portion. The level of the convex portions is lower than that of the corner cutting edges. Further, the reinforcing part of the present invention has flat portions that come into contact with the convex portions of the cutting insert at each corner portion. When the cutting insert and the reinforcing part are assembled together, the flat portions of the reinforcing part contact at least three convex portions of the cutting insert.

摘要： A tool holder has an apparatus for clamping a cutting insert thereto. The tool holder has a cutting insert pocket and a mounting bore; a clamp lever including a clamp portion and a lever portion placed in the mounting bore; and a fixing screw. The fixing screw is fastened through a hole which extends downwardly from a side wall of the tool holder to the mounting bore. One end of the fixing screw further includes a pressure-applying surface substantially perpendicular to the rotational axis of the fixing screw, and the side surface of the lever portion of the clamp lever has an inclined surface which makes contact with the pressure-applying surface of the fixing screw. According to the clamping apparatus, the cutting insert can be firmly clamped to the tool holder.
