I tried to drill a hole in a stainless steel pipe, but it can not be processed neatly. Besides, the tip of the drill was heated and turned red. I do not think it is a very cobalt drill. When you look at the stamp of the drill, it was only engraved with HSS. I do not have CO. This product is a scam. There is also the possibility that only the contents were exchanged. I can not trust this shop. I do not want to use it again.
