ECN Forum Forums General Topics of the Trade General Discussion Area Welders: Hardfacing old drill bits?

There are some cyro places that are kinda cheap. The prices were low enough at some I checked out to make me wonder if the bit gets any treatment at all, or is the treatment being applied to the payee instead? I got interested in this stuff a few years back after discussions with a motorhead neighbor who sends brake rotors and all sorts of stuff to the mainland to get treated. I looked into starting up a treatment shop right here, cause there isn't one in this state, but found the startup costs to be too high for our low population to make it work.
