I'm looking for a heavy duty knockout punch. Something that can punch a hole in 1/4 inch 316 stainless steel. Does anyone know where I can start looking for one?

Yeah one mistake people make with stainless is trying to just take light cuts because "stainless is tough", but all that does is work harden as you try to go in. You really have to push through the cut to ensure you're always reaching fresh steel.

If you're making dust instead of chips, slow the speed and get some more feed pressure
