Abstract:
A cutting insert includes a rake face extending along a cutting edge and a rising wall surface extending so as to form a recess along the cutting edge together with the rake face. The rake face is formed to have a positive rake angle, and includes a first rake face and a second rake face arranged in order in a direction in which a distance from the cutting edge increases. The second rake face is larger than the first rake face in rake angle.
