摘要： A cutting insert has a surface to be pressed and a surface to be restrained. A supporter has a supporter main body, an elastically deformable gripping arm, a pocket, and a slit. The supporter main body has a restraining surface that comes into contact with the surface to be restrained. The gripping arm has a pressing surface that comes into contact with the surface to be pressed. The slit has a pocket opening that is open to the pocket. The pocket opening is disposed between the restraining surface and the pressing surface.

摘要： A wiper insert includes three first corner portions and three second corner portions which are alternately aligned on a polygonal surface in an insert circumferential direction. A cutting edge has a first cutting edge that performs a finishing operation on a work material, and a second cutting edge. An outer peripheral surface has a first flank face, a second flank face, and a first restraint surface disposed outward from the second cutting edge in an insert radial direction. When viewed in an insert axial direction, an insert shape is rotationally symmetrical by 180° around a rotation center axis passing through the second corner portion adjacent to a first side of a predetermined first corner portion in the insert circumferential direction and an insert center axis.
