Depends on how big it is, what specific material it is, what you want to do with it, eg bore the inside diameter or plain turn the outside or form turn decorative rings on it etc.

Need more information to give a more specific answer. Otherwise it’s just a vague guess.

<p style=”text-align: left;”>Ah well  , if it’s already been bored and it’s definitely  gunmetal or some kind of  bronze  , run of the mill insert tooling should do the job. The ground inserts usually work best, eg xxGT rather than xxMT. Decorative ring as Noel said can perhaps use a HSS form tool ground from a blank on the bench grinder. Or even a small ball turning tool if the ring is semicircular in cross section.</p>

Where are all the graver users???

After following this forum for quite some time now this is the first time I’ve seen mention of a graver.

I don’t think they make carbide tips for one of those Bernard 🤣🤣🤣
