The thread former is used for the non-cutting shaping of threads and has a main body (1′) on which the moldings (6) are provided, distributed over the circumference. Said moldings are provided with thread-forming teeth (13, 14). Profile grinding tools are used to produce the thread-forming teeth (13, 14), both in the main body (1′) as well as in the moldings (6). In order for the thread former to be produced easily and cost-effectively, the moldings (6) protrude radially beyond the main body (1′) so far that the profile tool only engages with the molding when producing the thread-forming teeth (13, 14). Consequently, the profiling tool only has to machine one type of material. The thread former is used for the non-cutting shaping of threads, particularly of internal threads.
