<p>The present invention relates to a cutting insert with a cutting edge. The cutting insert includes a rake face (24) extending along a cutting edge (22a, 22b) and a rising wall surface (32a) extending so as to form a recess (34) along the cutting edge (22a, 22b) together with the rake face (24) . The rake face (24) is formed to have a positive rake angle, and includes a first rake face (24a) and a second rake face (24b) arranged in order in a direction in which a distance from the cutting edge (22a, 22b) increases. The second rake face (24b) is larger than the first rake face (24a) in rake angle. FIG. 4</p> |
