Sold in a \u003cb\u003e12-pack\u003c\/b\u003e, these HP-shank stones are the industry standard for finishing chrome-cobalt and nickel-chrome frameworks.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eWhat makes these \"Coral\" stones a lab favorite is their \u003cb\u003ecarbon-free aluminum oxide\u003c\/b\u003e 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.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eEach 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.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eProduct Highlights:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul style=\"margin-top: 0in;\" type=\"disc\"\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\"\u003e\n\u003cb\u003eShape:\u003c\/b\u003e #3 Mounted Point\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\"\u003e\n\u003cb\u003eShank:\u003c\/b\u003e HP (Handpiece) for laboratory use\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\"\u003e\n\u003cb\u003eMaterial:\u003c\/b\u003e Carbon-Free Aluminum Oxide (prevents metal pollution)\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\"\u003e\n\u003cb\u003eQuantity:\u003c\/b\u003e 12 per package\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\"\u003e\n\u003cb\u003eBest For:\u003c\/b\u003e Non-precious alloys (Chrome-Cobalt, Nickel-Chrome)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shofu","offers":[{"title":"Default Title","offer_id":43960389107755,"sku":null,"price":22.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1538\/0781\/files\/WhatsAppImage2026-04-21at10.03.56AM.jpg?v=1776780386","url":"https:\/\/www.alvydental.com\/products\/shofu-coral-stones-483a","provider":"Alvy Dental ","version":"1.0","type":"link"}
