    I have a diamond tool, the diamond is quite large and flat, I've machined Ali several times with it, mirror finish, light cut and lathe flat out, I'm told to avoid interrupted cuts, works well on copper too.

      concerning interrupted cuts, i own a single ceramic insert and use it for hard turning chuck jaws. its still like new, but what bobw53 said about speed. the insert has a single edge and was around $100, a "special" price a shop made me, because they didnt need it. so no idea if that works with any inserts out there.

      btw, how do you tell a reinforced insert? because its black?

        Pricing and having only one edge suggest that its a cbn- insert.
