Chapman is the best, and is priced likewise. Love them, can't afford to do what I'd really like to do. Buy one of everything they have! Still may need to grind one to fit, though.Chapman is the bees knees. I read somewhere that they make all the Brownells bits too and that probably explains why the Brownells are so well liked. Pricey, made out of tool steel, machined, made in USA. I'll pay some extra for that.
