FIELD: cutting threads, cutting and bending pipes. SUBSTANCE: device includes change head of thread-cutting tools for inner and outer diameters of pipes, change cutting head with roller or cutter, change head of helical bending device. Device is connected with high-speed small-sized single-phase commutator motor for supply through reduction gears. Housing of last reduction gear is rigidly connected with body of pipe retainer for feed of pipe during turn of self-grip pipe wrench. retainer has wedge-shaped surface for turn of self-grip pipe wrench. Retainer provides for motion of wrench together with gripped pipe in straight line along axis of pipe to exclude its rotation and to hold it in cutting. EFFECT: ease in use and feeding pipe for cutting first turns of thread. 3 cl, 2 dwg
