Abstract (en)

[origin: WO9856528A1] The present invention relates to an endmill provided with cutting edges of cBN or PCD and consisting of a shank part and a part containing the cBN or PCD brazed to the shank. The latter part is in the form of a disc in which the superhard material is present in a groove in the envelope surface and extends from one end surface to the other. After brazing the disc to the shank, the body obtained is ground to an endmill with cutting edges formed of superhard material. In a preferred embodiment, the shank is provided with a tenon against which the part containing the superhard material is brazed. This minimises the risk of braze joint failure and provides an endmill with several cutting edges which can be achieved at a low cost.
