Abstract
An indexable insert has a rake face on which a first ridge () and a second ridge () are provided. The first ridge () protrudes from a boss surface () towards a nose, and the second ridge () extends continuously from the first ridge () to a slope () connected to a cutting-edge land () of a linear cutting edge (). The second ridge () has a height lower than that of the first ridge () 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.
