<p>A tool for working the end (F) of a pipe (T) for the transport of fluids with smooth surface, comprising a support structure (2) defining a second axis (Z) and at least one couple of substantially C-shaped jaw elements (3, 4) with concavities reciprocally facing each other in order to define a seat (S) for housing the pipe (T). The tool includes also a first circular blade element (12) and a blade holder element (20) sliding along a third axis ( Z' ) substantially parallel to said second axis (Z) and substantially orthogonal to the first axis (X) defined by the pipe (T) on which the same circular blade element (12) is mounted. The blade holder element (20) includes also at least a second elongated blade element (19, 19') usable as alternative to the first circular blade element (12). The second elongated blade element (19, 19') defines a fourth axis (X') substantially parallel to the first axis (X) ansd substantially coinciding with the rotation axis of the circular blade element (12). The second elongated blade element (19, 19') includes an outer wall (22) comprising a first cutting edge (23) intended to come in contact with the pipe (T) in order to countersink the inner edge and a second cutting edge (23') susceptible to come in contact with the pipe (T) in order to chamfer the outer wall.</p> |
