摘要： The present invention relates to an indexable milling insert and a milling tool for chip removing machining. The milling insert is intended to be able to mill substantially perpendicular corners in a work piece. The milling insert (10) comprises an upper side (11 ), a lower side (12) and edge surfaces (13A,13B,14A,14B,15A,15B) extending there between. The upper side (11 ) and the lower side (12) are substantially identical. An imaginary circle (C) inscribed in the milling insert (10) touches the milling insert periphery in four to six points (S1 ,S2). Lines of intersection between the edge surfaces and the sides form relative to each other substantially perpendicular main cutting edges (16) and minor cutting edges (17). Each of the side (11 ,12) includes a support surface (18,19), each of which being provided in a plane (P1 ,P2). Each minor cutting edge (17) projects from the plane (P1 ,P2) of the associated support surface (18,19). Each major cutting edge (16) intersects the plane (P1 ,P2) of the associated support surface.
