{"product_id":"tungsten-vanadium-17-degree-fine-cut-cone-bur","title":"The 17-Degree Bur","description":"\u003cp\u003eThe 17 degree bur matches the standard 17 degree taper found on most round tapered prong and bezel settings to a shank. It solves the problem of having to hand file the correct profile on a shank to match a setting's profile: drill the shank with this bur and the result is a clean, accurate fit with no rocking, no gaps, and in most cases no need for secondary correction.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eThe 17 Degree Bur is engineered to solve one of the most common fitting challenges in stone setting work. Standard tapered prong and bezel settings have a natural taper that rarely matches a straight drilled hole, requiring time-consuming hand filing to achieve a proper seat. This bur eliminates that extra step.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003cp\u003eMade exclusively for Otto Frei in Germany, this 17 degree cone shape bur is mounted on a 3\/32\" (2.35mm) shank and is ready for use in any quick change or adjustable chuck flex shaft handpiece or micromotor handpiece.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePrecision 17 degree cone angle matches the taper on most standard prong and bezel settings when drilling shanks\u003c\/li\u003e\n\u003cli\u003eEliminates the need to hand file a straight drilled hole to match a tapered setting\u003c\/li\u003e\n\u003cli\u003eStandard fine cut for controlled material removal and a clean finished seat\u003c\/li\u003e\n\u003cli\u003eTungsten Vanadium construction for durability and consistent cutting performance\u003c\/li\u003e\n\u003cli\u003eMounted on a 3\/32\" (2.35mm) shank\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eThe 3\/32\" (2.35mm) shank fits any quick change or adjustable chuck flex shaft handpiece or micromotor handpiece.\u003c\/p\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43584887816406,"sku":"119.848","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/119.848NEW1_thumb_adccb465-e8bd-4431-9fa8-a293dc4febc7.jpg?v=1784159375","url":"https:\/\/www.ottofrei.com\/ja\/products\/tungsten-vanadium-17-degree-fine-cut-cone-bur","provider":"Otto Frei","version":"1.0","type":"link"}
