| description | A cutting insert has a top surface, a seating surface, and an outer peripheral surface. The cutting edge includes a corner cutting edge portion, a first cutting edge portion, and a second cutting edge portion. The top surface includes a first rake face, a second rake face, a third rake face, a front side surface, an upper surface, a first side surface, and a second side surface. The front side surface is located opposite to the corner cutting edge portion relative to the third rake face and rises from the third rake face. The upper surface is located opposite to the third rake face relative to the front side surface and is continuous to the front side surface. The first side surface is located opposite to the first cutting edge portion relative to the first rake face and rises from the first rake face. The second side surface is located opposite to the first rake face relative to the first side surface, is inclined relative to the first side surface, and is continuous to each of the first side surface, the front side surface, and the upper surface. A ridgeline between the first side surface and the second side surface is continuous to the upper surface. When seen in a direction perpendicular to the seating surface, a width of a boundary between the front side surface and the third rake face is larger than a width of a boundary between the front side surface and the upper surface. |
