Product Description:

The Shofu Coral Stones #483A (Shape #3) are high-performance laboratory stones specifically engineered for the heavy-duty contouring of non-precious and semi-precious metal alloys. Sold in a 12-pack, these HP-shank stones are the industry standard for finishing chrome-cobalt and nickel-chrome frameworks.

What makes these "Coral" stones a lab favorite is their carbon-free aluminum oxide composition. Because they are pure, they won't contaminate the metal surface during grinding—a critical factor if you plan to bond porcelain to the framework later. They cut aggressively yet smoothly, allowing you to refine the anatomy of a bridge or the clasp of a partial with total control.

Each stone is manufactured with high concentricity, meaning they spin perfectly centered without the "chatter" or vibration that can fatigue your hand or lead to imprecise results. The #3 shape provides a versatile mounted point that is large enough for bulk reduction but tapered enough for detailed shaping.
