Spearhead High Speed Steel (HSS) inverted cone burs are hand cut by expert craftsmen in the USA. Each bur features the size stamped directly on the 3\/32\" shank, making identification quick and reliable at the bench. While HSS burs carry a higher price point than imported Tungsten Vanadium Carbon Steel burs, their superior hardness delivers a longer service life and sustained sharpness that machine-cut alternatives cannot match. These burs are the preferred choice of quality jewelers.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHand cut by expert craftsmen in the USA\u003c\/li\u003e\n\u003cli\u003eHigh Speed Steel construction for superior hardness and extended service life\u003c\/li\u003e\n\u003cli\u003eStays sharper longer than machine-cut Tungsten Vanadium Carbon Steel burs\u003c\/li\u003e\n\u003cli\u003eSize stamped on the 3\/32\" shank for easy, reliable identification\u003c\/li\u003e\n\u003cli\u003eInverted cone profile for precise metalworking applications\u003c\/li\u003e\n\u003cli\u003ePreferred by quality jewelers for professional results\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAvailable Options\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eBur Size\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e119.635\u003c\/td\u003e\n\u003ctd\u003e1.70mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e119.638\u003c\/td\u003e\n\u003ctd\u003e2.30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e119.643\u003c\/td\u003e\n\u003ctd\u003e3.30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e119.649\u003c\/td\u003e\n\u003ctd\u003e4.70mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e119.656\u003c\/td\u003e\n\u003ctd\u003e6.30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e119.660\u003c\/td\u003e\n\u003ctd\u003e8.00mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Spearhead","offers":[{"title":"1.70mm","offer_id":43696775332054,"sku":"119.635","price":5.35,"currency_code":"USD","in_stock":true},{"title":"2.30mm","offer_id":43696775397590,"sku":"119.638","price":5.35,"currency_code":"USD","in_stock":false},{"title":"3.30mm","offer_id":43696775430358,"sku":"119.643","price":8.25,"currency_code":"USD","in_stock":true},{"title":"4.70mm","offer_id":43696775463126,"sku":"119.649","price":9.3,"currency_code":"USD","in_stock":false},{"title":"6.30mm","offer_id":43696775495894,"sku":"119.656","price":9.75,"currency_code":"USD","in_stock":true},{"title":"8.00mm","offer_id":43696775528662,"sku":"119.660","price":9.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/high-speed-steel-inverted-cone-burs-1-70mm-8-00mm-otto-frei.jpg?v=1719955420","url":"https:\/\/www.ottofrei.com\/ja\/products\/spearhead-hss-inverted-cone-burs-1-70mm-8-00mm-3-32-shank","provider":"Otto Frei","version":"1.0","type":"link"}
