摘要： A cutting insert has an upper face and a lower face; a front side face portion and a back side face portion, the front and back side face portions connecting the upper face and the lower face; and a through-hole passing through the upper face and the lower face. A cutting edge is formed in the front side face portion, and the back side face portion is provided with a first inclined face and a second inclined face which are inclined forwardly at different angles, respectively, with respect to a plane normal to a rotational axis. The first inclined face is longer than the second inclined face so that the back side face portion has a non-symmetrical convex "V" shape.
