- I thought I covered it so let me correct that mistake now. - It's GREAT. It drills Type 304 stainless steel FAST , even *with* frequent stops to avoid overheating I've tried many other bits and this one is the best, it's probably out of my price range This hard working bit was surprisingly cheap considering what it's for it was. I just wish they would make it 1/32" too - that would be great!
