Abstract

The present invention relates to a composite metal cutting insert consisting of cemented carbide having in the corners CBN bodies metallurgically bonded to an unground surface of the cemented carbide. The CBN-bodies have a thickness, T, of 0.5 to 2 mm, extend along the cutting edge on both sides of the nose, L2, 2-6 mm, with the length of the CBN along the rake face perpendicularly to the edge, L1, 0.5-2 mm. The length along the cutting edge consisting of cemented carbide, d, is at least 2 mm and the distance between two opposite CBN-bodies situated in the top and bottom surfaces, H, is at least 0.5 mm. The invention also relates to a method of producing such inserts.
