Stainless steel parting
Tuesday, 11 October 2016  |  Daniel

I've not had much luck with my parting tool in stainless and as a last ditch attempt, before trying other methods, I thought I'd give these a go. Like knife through butter, no chatter, no binding, just let the powered cross feed do the work along with a little cutting fluid. Much impressed.
