FIELD: manufacture of small-size (up to 3 mm) cutting tools of high speed steel. SUBSTANCE: in order to provide hardness of cutting tool HPC equals to 63-65, tool blank is deformed by high temperature gaseous extrusion at deformation rate 85-98% and temperature 820-1210 C. Heating and deforming processes are realized simultaneously. Deformed blank is quenched and then it is subjected to three-stage annealing. EFFECT: increased strength of tool, lowered cost price and labor consumption of manufacturing process. 1 tbl
