Thread die, formed by a steel block that has a hole with threaded cutting edges at its center and is split to be able to adjust exactly the diameter of the thread cut by these edges, characterized in that a conical hole is made in the slot thread in which is lodged an equally conical screw, so that by screwing this screw the edges of the slot of the tap are separated increasing the diameter of the central hole and loosening or unscrewing the screw, the slit is closed by the natural elasticity of the block steel that forms the tap, decreasing the diameter of the central hole.
