Sorry but this bit is overpriced and ineffective to say the least. It literally had trouble with three holes in 14 gauge sheet metal cheap general purpose bit I've used for hundreds of holes and I'll say that I'm on par with a commonly used bit and not a new one. I ended up with a high performance cobalt Bosch bit that really delivers!
