Abstract
A tool and related method for the non-cutting production or reworking of a thread in/on a workpiece comprises a forming area which is rotatable about a tool axis (A), the forming area having a plurality of pressing lobes protruding or projecting radially outwards away from the tool axis (A) for producing or post-reworking the thread by pressing the pressing lobes into the workpiece surface. The pressing lobes are arranged in succession along a shaping curve which substantially spirally encircles the tool axis (A), and the pitch of the shaping curve corresponds substantially to the pitch of the thread to be produced or reworked. The pressing lobes form at least one pressing ridge, wherein adjacent to the at least one pressing ridge a flaring ridge with a lower height Hthan the height of the pressing ridge His formed.
