Abstract:
1. A cemented carbide insert, comprising: an upper side; an under side; a plurality of side surfaces extending between the upper side and the under side; and an inset including a cutting edge, the cutting edge comprising a nose edge and two main edges converging toward the nose edge, the inset being formed of a material that is harder than the cemented carbide, and being countersunk in the surrounding cemented carbide and co-ground with the surrounding cemented carbide, wherein the inset is arranged in a front, wedge-shaped head delimited by one chip surface and two clearance surfaces running along the main edges, the head transforming into adjacent side surfaces and an adjacent intermediate surface via limiting surfaces situated inside imaginary planes in an extension of the chip surface and an extension of the clearance surfaces, and wherein the limiting surfaces are non-parallel to a mounting axis of the insert.
