Hi all....I need to cut a 1/8" slot in a piece of stainless steel ( I don't know what type of stainless it is...it came with a PM Research kit). I was going to use a slit saw, but I'm not sure which one to use and at what RPM to run at. One of the slit saws is 3" X 1/8" 30T , the other is 1 1/2" X 3/32 36T. The slot needs to be .433" deep. Also, I'm not sure if I should do the in 1 pass or do it 2 or more. Attached are photos of the saws. Any opinions or advice would be greatly appreciated. Thanks.
