%X Goal: Low wolfram-containing cutting composite was obtained by fusion of titanium carbonitride and high melting temperature binding metallic phase. Method: The composite was obtained via compaction and further sintering in vacuum furnace at 1600°C under 10-3 Pa pressure. Phase analysis was performed on X-ray apparatus ¡°DRON-3¡±; microstructure was determined by electron microscope NANOLAB-7, microhardness by MUCKE-mark microhardness meter; relative resistance of cutters was evaluated at similar modes of cutting according to distances they passed; experiments were carried out on turning lathe. Results: Physical-mechanical characteristics of the obtained composite are: ¦̉bend, = 1000 - 1150 MPa, ¦̉bend1000°C = 600 MPa, HV = 14 GPa; HV1000°C = 6.5 GPa. High speeds of cutting and high temperatures resistance of cutters made by the obtained composites exceeds 1.5 - 2-folds that of cutters made of the known BK8 and KNT20 hard alloys. Conclusion: Its application is recommended in hot steel treatment by cutting, for removal of the so-called burrs, as well as in steel treatment by cutting during pure and semi-pure operations. It can also be used in jet engines, chemical industry apparatuses, electric-vacuum devices, in industry of responsible details of rockets, nuclear reactors, flying apparatuses.
