A die that is essentially characterized by being constituted by a tubular inner body, whose internal surface has three stages of progressively increasing diameter, the smaller diameter corresponding to the entrance mouth, where a guide washer can be coupled, while the largest belongs to the exit mouth, to which the bearing or tool that tills the thread is adjusted, including on the external surface of the body itself, next to the entrance mouth, a chamfer followed by a cylindrical section equipped with a crown of straight teeth, near which there is a protrusion near a threaded end intended for the adjustment of a cover that holds and blocks the bearing or tool, being surrounded by the said body by another ring, which is located surrounding the crown of straight teeth, on which acts a trigger or ratchet lodged inside. A cylindrical chamber emerging from the periphery of that same annular outer body and which is next to a mouth to which a handle is attached, said trigger having a nail with impeller plane and curved or exhaust back, which allows it to jump on said teeth when that nail recedes, immediately returning to the advancing position in front of the posterior tooth by the action of a spring located inside the cylindrical chamber and which constantly compresses said ratchet nail.
