Abstract: The invention concerns a process for the manufacture of a cutting insert (1) for thread cutting, with several cutting teeth (2-6) simultaneously engaged in incrementally cutting the thread profile. The blank is manufactured by pressing and sintering so that the relief angles of the flanks of the side cutting edges (9,10) of the individual teeth (2-6) are at least 3.degree. and the profile depth of the final cutting tooth (6) which makes the finishing cut on the thread fits within the required final measurement tolerances, while the thickness of the cutting insert (1) and the tooth width (b) of the cutting teeth (2, 3, 4, 5, 6) are oversized. Subsequently, the blank is mechanically processed on the back face (7) and/or the front face (8) until the tooth width (b) of the cutting teeth (2, 3, 4, 5, 6) and the thickness (d) of the cutting insert (1) fit within the required final measurement tolerances.
