Medium Blue Zirconia Platinum Sanding Discs

These medium-grit zirconia discs are the perfect intermediate tool for refining platinum surfaces after the initial rough shaping is complete. They provide a controlled abrasive action that smooths out heavy scratches while preparing the metal for the final stages of finishing. Because platinum requires a more aggressive approach than gold or silver, these specialized discs save the jeweler a significant amount of time and effort at the bench. The durable bonding agent ensures that the grit stays on the disc longer, even under the high heat generated by the friction of working with dense white metals.
