The nose cutting edge (10) connects the first (11) and second (12) cutting edges. The first (11) and second (12) cutting edges forms a nose angle (α) of 71-85° relative to each other. The nose portion (15) comprises a third convex cutting edge (60) adjacent to the first cutting edge (11) and a fourth cutting edge (61) adjacent to the third convex cutting edge (60). The fourth cutting edge (61) forms an angle (β) of 10-30° relative to a bisector. The distance from at least a portion of the fourth cutting edge (61) to the reference plane (RP) is increasing at increasing distance from the nose cutting edge (10). A second protrusion (44) is arranged between the nose cutting edge (10) and the first protrusion (30).
