摘要： A cutting insert includes an insert body portion and a plurality of projecting portions provided integrally with the insert body portion. The projecting portion includes a cutting edge and includes projecting portion upper and lower surfaces, two projecting portion side surfaces, and a projecting portion side end surface extending therebetween. In the projecting portion, a round corner surface extends between the projecting portion upper surface and the projecting portion side end surface. The cutting edge is formed so as to include a corner formed along an edge of the round corner surface and such that the projecting portion side surface serves as a rake face. The projecting portion is designed such that a length between the two projecting portion side surfaces is smaller than a diameter of an inscribed circle defined on the insert body portion.
