Wrong size I ordered 3/32 and 5/64, they both came in 3/32, even the packaging said they were 5/64 should, but that wasn't a buyer, be careful, check your sizes, I've compared them to my other 5/64 bits and drilled the holes that don't match the big ones. One shaft says 3/32, the other only says #39, size not listed. However size 3/32 came as advertised and I also bought another 7/64 bit from them as my last one broke in some wood I was drilling. I think I got it to hot transition from one hole
