摘要

An insert 10 for metal turning and grooving has an annular cutting edge 19. A chipformer surface 20 is disposed radially inside of the cutting edge 19. A chip breaking wall 27 is disposed radially inside of the chipformer surface 20. The chip breaking wall 27 is inclined upwardly. A first section 27A of the chip breaking wall 27 located adjacent a front end 16 of the insert 10 has a steeper inclination than a second section 27B thereof spaced circumferentially from the first section 27A in a direction toward the rear end 15 of the insert 10. The inclination of the chip breaking wall 27 varies progressively from the first section 27A to the second section 27B.
