FIELD: methods of cold working of metals by plastic deformation on metal cutting machine tools, in particular, machine tools of the lathe group. SUBSTANCE: method consists in that blank cylindrical in shape is rotated and fed through threading rolls installed diametrically with respect to blank at different angles of crossing. Passing between rolls which move at different axial feeds to cause their mutual slipping, the blank proves to be under effect of stretching force that results in intensification of metal flow. The tool has body with cover, threading rolls located between them on axles in bearings of cover and body. Rolls are installed at different angle of crossing relative to feed axis. EFFECT: increased productivity due to increased diameter allowances by intensification of axial flow of metal. 2 cl, 2 dwg
