FIELD: tool making industry, in particular, tools for cutting outer thread. SUBSTANCE: composite threading die has body with radial slots 5 for receiving threading combs 1-4 which have threading profile recesses positioned at right side with spacing of Pp=Pк+ΔP,, and at left side with spacing of Pl=Pк-ΔP,, where ΔP is calibrating part space variation value. Threading combs have corrugated angle of groove profile on chip-receiving part less than that of calibrating part. EFFECT: increased efficiency and enhanced reliability in operation. 3 dwg
