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 internal groove insert includes a rectangular main body having a top surface, a lower surface, and first to fourth lateral surfaces; and first and second projections each projecting from the adjacent first and second lateral surfaces. The first projection has a first cutting edge at the side of the top surface of the main body, while the second projection has a second cutting edge at the side of the lower surface. The first and fourth lateral surfaces are inclined by an obtuse angle with respect to the top surface, while the second and third lateral surfaces are inclined by an acute angle with respect to the top surface. The central axis of the clamping hole is inclined to be parallel to the insert corner edge where the first and fourth lateral surfaces meet.
