Hi Ed,

It is rock hard stainless steel, Probably need a grinder like a cut-off
wheel in a dremal tool or die grinder.  Forget a hole saw unless it has
cobalt alloy teeth no normal saw or drill bit will touch it.  Once cut, a
belt sander can finish the edge.  I'll probably try it all an a little
cheap one first.  If I were really desperate, I would have it waterjet cut.

Cheers,

         Terry
