Inverted cone burs are among the most popular burs used in the jewelry industry, and the set gives jewelers and metalsmiths that range in one package.\u003c\/p\u003e\n\u003cp\u003eMachine made to ultra-high precision tolerances, Tungsten Vanadium steel burs are uniformly consistent from piece to piece, cutting with no chatter or drag. That is a key advantage over High Speed Steel (HSS) burs, which are individually hand cut, meaning no two are exactly alike. The most modern manufacturing equipment combined with Swiss steel hardening expertise makes these burs consistent best sellers. Tungsten Vanadium burs deliver excellent precision and value, but they are generally not as long lasting as USA-made High Speed Steel burs.\u003c\/p\u003e\n\u003cp\u003eEvery bur in the set has a \u003cstrong\u003e3\/32\" diameter shank\u003c\/strong\u003e, and the kit is stored in an included round plastic holder for organized bench access.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e14-piece inverted cone bur set in a single kit\u003c\/li\u003e\n\u003cli\u003eSwiss-made Tungsten Vanadium steel construction\u003c\/li\u003e\n\u003cli\u003eMachine made to ultra-high precision tolerances for consistent, uniform cutting\u003c\/li\u003e\n\u003cli\u003eCuts precious metal smoothly and cleanly with no chatter or drag\u003c\/li\u003e\n\u003cli\u003eCovers a wide size range of 0.60mm – 2.90mm\u003c\/li\u003e\n\u003cli\u003e3\/32\" diameter shanks fit standard flex shaft handpieces and rotary tools\u003c\/li\u003e\n\u003cli\u003eRound plastic holder included for organized storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eThe 3\/32\" shanks fit standard flex shaft handpieces and rotary tools that accept 3\/32\" shank burs.\u003c\/p\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eThe kit contains the following burs and holder:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.537\u003c\/strong\u003e – Inverted Cone Bur, 0.60mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.538\u003c\/strong\u003e – Inverted Cone Bur, 0.70mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.539\u003c\/strong\u003e – Inverted Cone Bur, 0.80mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.540\u003c\/strong\u003e – Inverted Cone Bur, 0.90mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.541\u003c\/strong\u003e – Inverted Cone Bur, 1.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.542\u003c\/strong\u003e – Inverted Cone Bur, 1.20mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.543\u003c\/strong\u003e – Inverted Cone Bur, 1.40mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.545\u003c\/strong\u003e – Inverted Cone Bur, 1.60mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.546\u003c\/strong\u003e – Inverted Cone Bur, 1.80mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.547\u003c\/strong\u003e – Inverted Cone Bur, 2.10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.548\u003c\/strong\u003e – Inverted Cone Bur, 2.30mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.549\u003c\/strong\u003e – Inverted Cone Bur, 2.50mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.534\u003c\/strong\u003e – Inverted Cone Bur, 2.70mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e118.535\u003c\/strong\u003e – Inverted Cone Bur, 2.90mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e119.248\u003c\/strong\u003e – Round Plastic Holder\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei Swiss Burs","offers":[{"title":"Default Title","offer_id":43582560501974,"sku":"118.002","price":24.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/swiss-inverted-cone-bur-kit-14-piece-0-60mm-to-2-90mm-otto-frei.jpg?v=1719956986","url":"https:\/\/www.ottofrei.com\/ja\/products\/swiss-inverted-cone-bur-kit-14-piece-060mm-290mm","provider":"Otto Frei","version":"1.0","type":"link"}
