The device refers to a cutting and chamfering tool for pipes, preferably of plastic material, composed of single-bladed elements (4, 5), fixed on a ring (1) with a greater diameter than the pipe (3) and oriented toward the centre of the ring and such that during working, the pipe is on the inside of the ring and parallel thereto; a first category (4) of these elements, designed for cutting and composed of functionally identical units, being disposed on different radial directions and equidistant from the centre, and a second category (5) thereof, designed for chamfering and also composed of functionally identical units, being disposed on different radial directions and equidistant from the centre; and the overall profile generated axially by the movement of the two categories of tools (4, 5) corresponding to the axial profile of the cutting and chamfering planned on the pipe (3). <IMAGE> |
