FIELD: process engineering.SUBSTANCE: invention relates to machine building and can be used for making of single-piece cutters. This comprises body, at least one cutting edge at its front and core hot fitted in said body to extend to cutter front end. every cutting edge is made, at least partially, of core material. Contact surface results to dissipate the cutter bending stresses in operation.EFFECT: higher stiffness, process efficiency, longer life.15 cl, 4 dwg |
