ABSTRACT:
A milling cutter for chip removing machining includes a milling cutter body with a number of insert pockets in connection with an end of the milling cutter body. An opposite end of the milling cutter body is adapted to cooperate with a tool attachment. An indexable cutting insert is secured in the cutting insert seats, each indexable cutting insert having two substantially identical main surfaces. Two side surfaces and two end surfaces extend between the main surfaces, each main surface including two cutting insert corners, each cutting insert corner including major cutting edge and a minor cutting edge. Parts of each main surface include rake faces. Parts of each side surface and each end surface include clearance surfaces. The cutting insert has a height between the end surfaces and each main surface includes an associated support surface. A perpendicular distance of each main cutting edge to a plane that coincides with the support surface facing away from the main cutting edge increases in a direction from the cutting corner to a crest in the area of a half height of the indexable cutting insert.
