Abstract (en)
[origin: WO9309896A1] A non-cutting tool is disclosed for producing workpiece inner and outer profiles, in particular inner and outer threads. The tool has several elements (1) arranged in such a way in their initial position that they may be inserted into the workpiece. In addition, a spreading element (3) is provided that moves the tool elements (1) in a direction essentially perpendicular to the surface or in a radial direction into an engagement position, in which the tool elements (1) are pressed on the workpiece (6) in such a way that no gaps are left between them and the desired profile is formed.
