FIELD: working materials by cutting, possibly turning elongated cylindrical parts with lowered flexural rigidity.
SUBSTANCE: tool includes holder in set of which cutter is mounted. Cutter has cutting edges in both its ends; one cutting edge id leading one, other cutting edge is lagging one. In order to enhanced efficiency of working due to elimination of blank bending, front surface of leading cutting edge crosses along chord outer surface of cutter; rear surfaces cross inner surface of cutter. Cutter has at least one additional cutting edge provided between leading and lagging cutting edges. All cutting edges are arranged inside through central opening of cutter. Front and back surfaces of additional cutting edge or edges cross inner surface of cutter.
EFFECT: enhanced efficiency of cutting process.
