Just bought a set of these

I wanted to drill a couple of 22mm and 32mm holes . Very cheap and Chinese, I was taking a gamble on how bad they were going to be but they just arrived so I tried a couple and amazingly they cut clean accurate holes and for the number of times I need holes this size (not a lot) they will do.
