Inverted cone burs are among the most popular burs used in the jewelry industry, and this kit gives jewelers and metalsmiths a comprehensive range of sizes in one convenient package.\u003c\/p\u003e\u003cp\u003eMachine-made to ultra-high precision tolerances, Tungsten Vanadium steel burs are uniformly consistent from piece to piece — cutting precious metal smoothly and cleanly with no chatter or drag. This 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. Note that while Tungsten Vanadium burs deliver excellent precision and value, they are generally not as long-lasting as USA-made High Speed Steel burs.\u003c\/p\u003e\u003cp\u003eAll burs in this set feature \u003cstrong\u003e3\/32\" diameter shafts\u003c\/strong\u003e and are stored in an included round plastic holder for organized bench access.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e14-piece inverted cone bur set in a single convenient 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 — no chatter or drag\u003c\/li\u003e\n\u003cli\u003eCovers a wide size range: 0.60mm – 2.90mm\u003c\/li\u003e\n\u003cli\u003e3\/32\" diameter shafts compatible with standard flex shaft handpieces and rotary tools\u003c\/li\u003e\n\u003cli\u003eIncludes a round plastic holder for organized storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eTungsten Vanadium Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eSwiss-made\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBur Type\u003c\/th\u003e\n\u003ctd\u003eInverted Cone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShaft Diameter\u003c\/th\u003e\n\u003ctd\u003e3\/32\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize Range\u003c\/th\u003e\n\u003ctd\u003e0.60mm – 2.90mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePiece Count\u003c\/th\u003e\n\u003ctd\u003e14 burs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\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\/products\/swiss-inverted-cone-bur-kit-14-piece-060mm-290mm","provider":"Otto Frei","version":"1.0","type":"link"}
