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