Claim:
1. A thread generating tool for producing a thread in a workpiece, having the features: a) the tool is rotatable about a tool axis (A), b) the tool has a number n≧1 of groove generating regions for generating in each case one groove in the workpiece and a number m≧1 of thread generating regions for generating the thread in the workpiece, c) each of the m thread generating regions is arranged behind one of the n groove generating regions as viewed in an axial projection parallel to the tool axis (A), and has a smaller extent than said groove generating region as viewed in cross section in the axial projection, d) wherein at least some of the n groove generating regions are formed as cutting groove generating regions with groove generating cutting edges, e) wherein each groove generating region has a groove cutting edge oriented toward or situated on the face side, f) wherein the groove cutting edges are the radially furthest outward projecting regions of the tool, at least in the front portion thereof, g) wherein the or each groove cutting edge is adjoined laterally in a circumferential direction by a side cutting edge, which is at the front in the direction of rotation (S) about the tool axis (A), h) wherein during the rotation of the tool in the direction of rotation (S) which takes place for the generation of the thread, the front side cutting edge cuts laterally into the workpiece.
