  • $\begingroup$ I suggest you don't make a die to punch a 0.009 " ( I only think in English) hole in tough stainless steel ( assuming 304 or 316 ). Are you trying to make a die for extrusion ? $\endgroup$ – blacksmith37 Mar 21 '18 at 21:54
  • $\begingroup$ @blacksmith37 when the question was asked in metric, why answer in imperial? Then double down when an explicit statement about it? $\endgroup$ – morbo Apr 15 at 10:25

You could "micro metal etch" the pattern either onto a stamp or onto a die. This kind of thing is done by these companies:
