I needed to enlarge an existing hole in a stainless steel sink for a dishwasher air vent. Using a conventional hole saw was not going to work as I had no center. This was the perfect bit for the job. I just used some light water, and sprayed the bit as I drilled. I was getting metal shavings, so I can say the bit was cutting, not just burnishing. I used a fairly slow speed on a half inch drill. Worked perfect for my application.
Do I think this bid could drill holes all day long in stainless? Absolutely not. If you have a few holes to do though these are probably a good value. I'm sure I can get a few more uses out of this as I only used one size. There's plenty of times where I need to enlarge a hole as I was off the first try, and these bits are really idea for enlarging an existing hole. I can't think of any other bit that would work as well.
It's kind of like an EZ-out. When you need it there's not much else that works as well, and I think that's the case for this bit. For me, it was the perfect solution.
