ABSTRACT:
The round cutting tool (10) comprises a substantially cylindrical shank (11), carrying a separately manufactured annular collar (14) slipped subsequently on the shank and abutting against a stop element (13). As a result thereof, material and energy costs are considerably reduced during the production of the round cutting tool because it is not produced in total in one piece in removing material by dressing.
