Take an old setting bur and grind the point off. Grind it down just past the edge that cuts the corner for the girdle of the stone. What you have left is a wheel bur with teeth on the edges only. (In essence a wheel bur with a safety edge.) With this you can trim the inside edge of a bezel setting to remove the wavy edge left from pushing it over the diamond. Cut carefully as to not remove very much metal. This will leave a smooth even edge that can be polished easily with a graver.
