A milling insert (100) and a milling tool (200) suitable for shoulder milling, wherein the milling insert comprises an upper side (101), a lower side (102), a side surface (104) extending between the upper side and the lower side and including a primary and a secondary clearance surface, and a cutting edge comprising a primary (108a) and a secondary cutting edge portion. The upper side has a basic shape of a parallelogram with a base defining a longitudinal direction along the primary cutting edge portion, and a height defining a lateral direction. The side surface comprises an axial support surface opposite of the secondary cutting edge portion. The lower side comprises a locking groove (111a) extending longitudinally, and a lower contact region formed to bear on a fastening member (300). The upper side comprises an upper contact region (114a) adapted to bear on a top support member of a tool in which the milling insert is mountable. The milling tool is provided with a top support member (207) for bearing on the upper contact region of the milling insert, a locking ridge (208) for locking with the locking groove, and an axial contact surface for supporting the axial support surface. The fastening member presses the milling insert against the top support member and the locking ridge. |
