摘要： The present disclosure can realize further prevention of a mounting mistake caused when a cutting insert is mounted on an insert seat is implemented by voluntarily improving a structure around the insert seat in particular. An insert mounting part has a shape including a bottom surface, a constraint surface that comes into contact with at least a part of a constraint target surface formed as a surface of a peripheral side surface of the cutting insert inclining with respect to an upper surface or a lower surface, an evacuation part that allows evacuation from the constraint surface hedging a cutting edge of the cutting insert, a first protrusion area that extends hiding a part of the upper surface or the lower surface of the cutting insert, a relief part that is formed at a part that a corner part of the cutting insert approaches so as to hedge the corner part, and a second protrusion area that extends from an upper side of the relief part so as to cover the part of the upper surface or the lower surface of the cutting insert mounted on the insert mounting part.

摘要： Chip discharge control is further improved. A cutting insert includes an upper surface, a lower surface, a screw hole having an axis penetrating from the upper surface to the lower surface, a peripheral side surface, and a major cutting edge, a wiper edge, and an inner edge formed in an intersecting region between the upper surface and the peripheral side surface. In a side view in which the peripheral side surface on which the inner edge is formed is seen from a direction perpendicular to the axis, the inner edge includes a recessed part recessed toward the lower surface, a length DL of the inner edge on one side of the recessed part in the side view is longer than a length DR of the inner edge on the other side of the recessed part, a lowest point of the inner edge is at a position lower than a flat part of the upper surface, and at least a part of the inner edge on the one side is at a position higher than the flat part of the upper surface. A cutting edge angle φ23L of the inner edge on the one side of the recessed part is larger than a half of a cutting edge angle φ23R of the inner edge on the other side of the recessed part.
