Abstract
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.
