For instance, use a barrel shaped polisher for the inside of rings rather than a small cylinder. The various shapes and points will get into nooks and crannies to give your entire work a brilliant luster. The item to be polished should be prepared by filing or sanding out any pits or scratches with bristle discs, sandpapers, etc. up to 400 grit. After the surface is pre-polished, install one of the Black (coarse) polishers in your rotary tool and polish the item until all evidence of the prior sanding is removed and the surface is uniform. Change the point to accommodate the shape needed to get into all areas you wish to polish. Knife edges will get into sharp inside corners, ledges and edges. Small tapers can get around prongs and into holes and in corners. Be careful with gemstones and other embedded items. The grit in these points is silicon carbide and will scratch many gemstones. The hardness of silicon carbide is 9.2 on the Mohs scale which means it will scratch everything but a diamond and some cubic zirconias.After polishing, it's always a good idea to buff with a polishing cloth to remove fingerprints.
