I would think. flip them upside down, hole punch a center hole hole, drill out from behind into a piece of wood with the hole saw, and then repeat would work well.

I agree with the others screw it to a pieces of wood then drill it out.....stainless requires slow cutting with lots of cutting fluid to keep it cool, or it work hardens and gets very tough to cut.

Thanks guys...The hole saw we used looked and felt like it was sharp but it was used and dont know the quality of it...I drilled a pilot hole in the center then turned it over ,laid it on a piece of wood in the drill press....used a moderate speed but it didnt cut.....I think I need a higher quality one thats made for stainless and try that ? It did get hot so maybe like you said it was a combination of dullness and using to fast of a speed.....Jim

A bit off topic: Stainless is also not so stainless in harsh environments, like down here in Kino Bay. If you don't dry the stainless sinks after each use, it starts rusting almost immediately. I have seen stainless down here completely rusted through, especially on the boats. The rain here is salty. That said, I still like things made of stainless...Mark

I saw my Uncle do a couple for me, seemed like they cut pretty easy, but don't remember if he used a special hole saw.

That will happen with some alloys. It depends on the amount of nickel in the alloy. When I was doing machine work we built environmental chambers that replicate weather cycles rather rapidly for scientific testing. We had to use the higher nickel fasteners and stock we machined. I don 't remember the alloy.as I suffer from CRAFT but it has softer and wanted to tear when machined. That said I think salt is the enemy of everything to some degree.

Yup, salt is the true enemy of the people (sorry). I just read that sodium in soda and salt itself are major components in bone loss in old age. In my youth, which went all the way to the age of 50, I drank nothing but soda. I probably went weeks without ever drinking any water. I figured that I wasn't dying of thirst, so it must be ok. Now at the age of 63, I know that my bones are not nearly as robust as they used to be. In my life, I have quit smoking, drinking and soda. Guess which was the hardest, yup, it was the soda. I absolutely love fully sugared Coca Cola, still do. I can't walk by an empty can of soda without thinking that just 1 would be ok. I drank one a few years ago and the next thing I knew, I was drinking pop again. It was much easier to quit the second time. I wonder if there is a popaholics anonymous...Mark P.S. I never got over weight because I ran 90 miles a month (6 miles 15 times a month) and that is the only reason that I didn't gain weight.

My wife says the main reason they put salt/sodium in drinks is to make you thirsty so you buy more. There is also salt in most bottled water. My was told that when she worked in a clinic.She went through a bunch of classes on nutrition Because she was a Spanish interpreter.for the county. I know what you mean about the old bones I have osteoporosis. from radiation treatments.
