Abstract

An indexable and double-sided round cutting insert for a milling tool, the cutting insert comprising an upper side (10) and a lower side (20), wherein a center axis (A) is extending between said upper and lower side (10, 20) and a median plane (P) is extending perpendicular to said center axis (A) and situated halfway between the upper and lower side. A side surface comprises an upper and a lower positive clearance surface (31, 32) at an upper positive clearance angle (±) with respect to an upper cutting edge (41) and a lower positive clearance angle (²) with respect to a lower cutting edge (42), wherein a plurality of protrusions (50) extend along said side surface (30) and protruding in a radial direction perpendicular to said center axis (A) of the round cutting insert. Each protrusion (50) comprising an outer surface (51), which in a direction along said center axis (A) is extending such that a first radial distance from said center axis (A) to said outer surface (51) in the median plane (P) of said insert is at least equal to or greater than a second radial distance from said center axis (A) to said outer surface (51) in parallel planes located closer to said upper or lower side of the round cutting insert.
