Abstract: A double-sided cutting insert includes two end surfaces that each includes major rake surfaces adjacent major cutting edges that form first angles with planes of major side surfaces of the insert, and a central support surface forming a second angle with the planes of the major side surfaces. Each end surface further includes major intermediate surfaces between the major rake surfaces and the central support surface. The major intermediate surfaces form third angles with the planes of the major side surfaces that are greater than the first angles and smaller than the second armies when measured in a central plane that extends along a central axis of the hole and is generally perpendicular to the planes of the major side surfaces and planes of the central support surfaces.

Abstract: A cutting insert is provided including at least three cutting edges, each cutting edge including a primary cutting edge. Each primary cutting edge is associated with a respective different side surface of the cutting insert, each side surface having a respective rake surface and a clearance surface. The clearance surface is of varying width.

Abstract: A milling cutter for chip removing machining includes a milling cutter body with a number of cutting insert seats in connection to a chip removing end of the milling cutter body, the milling cutter body being formed to cooperate with a tool attachment at its opposite end in the axial direction, wherein indexable cutting inserts are secured in the cutting insert seats, each the indexable cutting insert having a top surface and a bottom surface substantially parallel with the top surface, wherein side surfaces extend between the top surface and the bottom surface, the indexable cutting insert having the basic shape of a truncated pyramid. The invention also relates to a milling cutter body and an indexable cutting insert, per se. Each indexable cutting insert has its top surface facing against the chip removing end of the milling cutter, and main cutting edges of the indexable cutting insert extend from the top surface of the indexable cutting insert.
