Abstract
The invention relates to a thread forming tool having a thread part based on a helical effective surface (1), and an adjoining clamping shank (2), wherein the helical effective surface (1) is formed by pressing lobes (5) and the thread part extends from a chamfer or taper (6) in the direction of the clamping shank (2). Furthermore, at least one axially oriented, groove-like cooling channel (7) that runs between the pressing lobes (5) and extends from the chamfer or taper (6) to the clamping shank (2) is provided. According to the invention, the width of the at least one cooling channel (7) increases from the chamfer (6) in the direction of the clamping shank (2).

A thread forming tool comprising:
- a thread part on a helical effective surface;
- an adjoining clamping shank, wherein the helical effective surface is formed by pressing lobes and the thread part extends from a chamfer located at a tip of the thread forming tool in an axial direction of the thread forming tool toward the clamping shank, as well as having at least one axially oriented cooling channel that runs between the pressing lobes and extends from the chamfer toward the clamping shank,
- wherein the at least one cooling channel comprises a groove configured to receive and guide a coolant along the at least one cooling channel;
- and
- wherein a width of the at least one cooling channel continuously increases between the pressing lobes in the axial direction from the chamfer toward the clamping shank.
