ABSTRACT:
An indexable insert has a rake face on which a first ridge (2) and a second ridge (3) are provided. The first ridge (2) protrudes from a boss surface (1) towards a nose, and the second ridge (3) extends continuously from the first ridge (2) to a slope (8) connected to a cutting-edge land (7) of a linear cutting edge (6). The second ridge (3) has a height lower than that of the first ridge (2) and is convex-curved towards a bisecting line (CL) of an apex angle of the nose in plan view, thereby achieving both enhanced chip processability and reduction of load received when raking a chip.
