FIELD: process engineering.SUBSTANCE: invention relates to cutting tools. Particularly, it relates to radial cutter of header, header and method of cutter production. This cutter comprises shank, head and insert. Said shank features out-of-round cross-section. Said head comprises point area remote from shank and lateral surfaces connecting the front and rear surfaces. Insert is arranged at the point front end. Said insert has body made of tungsten carbide and element made of superhard material. The latter extends into said body and fused therewith. At least a part of superhard material element is exposed at insert cutting surface. At least a part of head front surface is made of superhard material and spaced from the element made of superhard material.EFFECT: better tool characteristics.22 cl, 34 dwg |
