T- T-SLOT CUTTER HAVING SEPARATE CENTERING AND TORQUE-TRANSMITTING PORTIONS

摘要

The cutting head 14 for the T-slot cutter 10 has an opposing cutting head upper surface and a cutting head intermediate surface 18, 20 extending perpendicularly to the head rotation axis A and a head peripheral surface 22). In addition, the cutting head 14 includes a cutting portion 24 and a head projection 32 that are located along the head peripheral surface 22. The head projection 32 extends from the cutting head intermediate surface 20 and includes a head torque transmission portion 42. The cutting head 14 further includes a cutting head abutment surface 34 and a head bore 36 coaxial with the head rotation axis A. [ The head bore 36 extends between the cutting head top surface 18 and the head protrusion 32 and extends to the cutting head top surface 18 and the head protrusion 32. The cutting head 14 also includes a head centering portion 40 that is different from the head torque transmitting portion 42 and is located at a different axial position from the head torque transmitting portion 42 along the head rotational axis A .
