Abstract
The description refers to a tool for the non-cutting production of outer and inner contours on workpieces and in particular of outer and inner threads. The tool has several tool elements which are arranged in a basic state such that the workpiece can be introduced into them, or vice versa in the case of inner threads, and a spreading element which transfers the tool elements to an engaging state by means of a movement which is largely vertical to the surface or in the radial direction, and the tool elements are pressed against the workpiece in such a way that they then form the desired contour without any interstice.
