Claim 7:
8. The cutting head (20) according to claim 7, wherein:
each secondary cutting-edge portion β2) has a secondary median point (NMS) located partway along its length, the three secondary median points (NMS) defining a fourth imaginary circle (C4) having a fourth diameter (D4),
the secondary median point (NMS) of one of the secondary cutting-edge portions (32) is contained in a fourth imaginary radial plane (PR4), and the fourth imaginary radial plane (PR4) contains the central axis A1,
