Abstract

A round cutting insert (1) for a milling tool having an insert centre axis (C₁) and a neutral plane (NP) extending perpendicularly to the insert centre axis (C₁). The round cutting insert includes a circumferential side surface (4) surrounding the insert centre axis (C₁) and extending between upper and lower round main surfaces (2, 3), wherein an upper cutting edge (6) is formed along the intersection of the upper round main surface (2) and the circumferential side surface (4), and a plurality of elongated support grooves (7) are arranged in the circumferential side surface (4). Each elongated support groove (7) has a bottom surface (8) extending in a lengthwise direction (L) with opposite flank surfaces (9a, 9b) converging toward the bottom surface (8) and extending in parallel with the lengthwise direction (L) of the elongated support groove (7). The lengthwise direction (L) of each elongated support groove (7) is forming an acute angle θ with the neutral plane (NP) as seen in a side view of the round cutting insert (1), and at least one of the opposite flank surfaces (9a, 9b) of each elongated support groove (7) is configured as a side support surface (9a) for the round cutting insert.
