A milling insert (100) for shoulder milling having a positive basic shape and comprising an upper side (101) comprising a rake surface (103), a lower side (102) comprising a planar bottom surface (105), a side surface (104) extending around the periphery of the milling insert, and a cutting edge (106) formed between the side surface and the rake surface. The cutting edge comprises at least a major cutting edge portion (107a, 107b), a corner radius cutting edge portion (108a, 108b), a ramping cutting edge portion (110a, 110b), and a surface wiping cutting edge portion (109a, 109b). The side surface comprises an upper set of primary clearance surfaces (111b) and a lower set of secondary clearance surfaces (115b) comprising a plurality of planar secondary clearance surfaces (115b), wherein the upper set of primary clearance surfaces forms an overhang protruding with respect to the secondary clearance surfaces and extending around the entire upper periphery of the milling insert. |
