For low volume work, what would you suggest?



A 10 ton press.

Now if you are handy, you can make up a punch and die for an arbor
press..at least a 15 tonner.

Stainless steel requires 1.5x the energy as standard steel to
punch/shear

Roughly. Often times a bit more.

What size work piece and where the holes are at, makes a big difference
as well


..375 H&H Magnum should do it. Be a little deburring to do, but for a
bunch of machinists like this, no problem. In fact, one might use a
somewhat smaller cartridge so the metal doesn't expand oversize in the
BAZ. Reaming would get the hole to exact size and take care of the
deburring at the same time.
