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?

Not if it's well lubricated.

I've cut hundreds of holes, and did not loose a blade in the kit.

As crude as they are, holes saws will last a long time and cut through a fair deal of depth material.

Anchor lube or tap magic are your friends
