Don,
sorry to make your fingers work so much, but i have a set of hole saws (had to buy them for all the holes in my firewall and the shower i put in the basement (remodeling the house)).. like you said stainless is another animal. thats what i didnt know what kind of blades you use ex bi metal. the ones i have worked pretty good for cutting the steel firewall but i dont think they will hold up on the stainless, and they arnt real cheap when you got to buy one for every hole. thank you again, and sorry.

thanks
Harmon
