Abstract
A cutting insert has first and second end surfaces, a peripheral side surface, a reference central axis A perpendicular to and passing through the two surfaces, and a cutting edge having at least one circular-arc-shaped cutting edge. A contact surface portion is formed in the second end surface. The arc-shaped cutting edge is part of virtual circle having a center E which is spaced apart from the central axis A. A longitudinal plane B includes the central axis A and the center E; a median plane C perpendicular to the central axis A passes midway between the two end surfaces; and a virtual plane D perpendicular to both the longitudinal plane B and the median plane C, intersects the circular-arc-shaped cutting edge and traverses the contact surface portion. In a cross-section along the virtual plane D, the contact surface portion is inclined relative to the median plane C.
