ABSTRACT In the manufacture of external and internal shapes from metallic material with cut faces free of break-offs, the stamping technique can be used only up to limiting values of D/S = 1 or A/S = 1 (D = hole diameter, S = material thickness, A = web or edge width). Nor does the conventional art of precision cutting achieve sufficient limiting values. The invention improves the known precision-cutting tools by doing away with the conventional knife-edged rings, instead of which the material to be precision-cut is supported, on its shell surface outside the cutting line by supporting members located at the side of the cutting punch. Limiting values, which it has been possible to achieve hitherto only by means of the much more expensive machine- cutting processes, are obtained as a result.
