The present invention relates milling inserts having surfaces designed for supporting of the insert relative to a milling cutter body, and a milling tool. The milling insert (21) comprises a first end surface (35), a second end surface (37), a side surface (39) extending between the first end surface (35) and the second end surface (37). At least one cutting edge (41) is defined by an intersection of at least one of the first end surface (35) and the second end surface (37) with the side surface (39). The at least one cutting edge (41) comprises a radiused component (45) having a first end (47) and a second end (49) and first and second components (51 and 53) at the first and the second ends (47 and 49) of the radiused component (45), respectively. The first and second components (51 and 53) are less curved than the radiused component (45). The side surface (39) comprises at least one substantially V-shaped valley (59) defined by first and second support surfaces (61 and 63). |
