Abstract
An indexable and double-sided round cutting insert includes an upper and lower side. A center axis extends between the upper and lower side and a median plane extends perpendicular to the center axis and is situated halfway between the upper and lower side. A side surface has an upper and lower positive clearance surface at an upper positive clearance angle with respect to an upper cutting edge and a lower positive clearance angle with respect to a lower cutting edge. A plurality of protrusions extends along the side surface and protrude in a radial direction perpendicular to the center axis. Each protrusion includes an outer surface, which along the center axis, extends such that a first radial distance from the center axis to the outer surface in the median plane is at least equal to or greater than a second radial distance from the center axis to the outer surface.
