Abstract
A tool for the chipless production of a thread on a workpiece can comprise a forming region, which is rotatable about a tool axis (A), for the chipless production of an internal thread, wherein the forming region has a plurality of pressure studs, which project radially from the tool axis (A), for producing or finishing the thread by pressing the pressure studs into the workpiece surface. In one implementation, the pressure studs are arranged successively along a shaping curve that encircles the tool axis (A) in a substantially spiral manner, and the pitch of the shaping curve corresponds substantially to the pitch of the thread to be produced. Additionally, the pitch angle (t) between first and second pressure studs along the shaping curve differs from the pitch angle (t) between the second pressure stud and a third pressure stud that follows the second pressure stud along the shaping curve.
