The present invention relates to a milling tool (10) and a cutting insert (11) therefore. The milling tool comprises a, preferably plate-shaped, milling body (30) intended to be rotated in a milling machine. The milling body comprises a plurality of insert pockets (41) in order to receive indexable cutting inserts (11). The cutting insert has a hole (18) for clamping. The cutting insert is double sided and has four pairs of cutting edges. Diametrically opposite cutting corners (17A, 17B) on different sides of the cutting insert (11), which each a has a pair of cutting edges (15A, 21A; 15B, 21 B), define a bisector (B), which bisector substantially intersects a centre (C) of the insert hole (18). Each pair of cutting edges (15A, 21A; 15B, 21B) is arranged at a distance from the milling body (30). The edge surfaces comprise parts (14C, 14D) providing positive clearances and being substantially parallel with each other. |
