The Busch Fig. 2K-AU carbide setting bur is engineered for exactly that work: when a stone is fitted into a square bezel, the edges of the gemstone and the corners of the setting are the critical areas, and the 2K-AU is designed to protect both.\u003c\/p\u003e\u003cp\u003eWhat distinguishes the 2K-AU from a standard setting bur is its \u003cstrong\u003esmooth, non-serrated front surface\u003c\/strong\u003e. That design prevents unwanted milling contact in the axial direction, so existing polished edges are not damaged during use. Where gravers cannot be applied to this work step, the 2K-AU offers an optimal alternative, letting the jeweler optimize the setting geometry to match the gemstone without risking edge damage.\u003c\/p\u003e\u003cp\u003eBeyond bezel fitting, the 2K-AU also suits grain setting work, including cutting out or separating individual grains and removing the bars between neighboring gemstones. Its carbide construction delivers the durability and precise control that professional stone setters demand.\u003c\/p\u003e\u003cp\u003eMounted on a 3\/32 in. shank and sold individually, in 10 sizes ranging from 0.60 mm–2.30 mm.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSmooth, non-serrated front surface prevents axial milling contact\u003c\/li\u003e\n\u003cli\u003eProtects polished edges and gemstone corners during setting\u003c\/li\u003e\n\u003cli\u003eIdeal for princess cut diamonds and other angular gemstones in square bezel settings\u003c\/li\u003e\n\u003cli\u003eSuitable for grain setting, separating grains and removing bars between stones\u003c\/li\u003e\n\u003cli\u003eCarbide construction for durability and precise performance\u003c\/li\u003e\n\u003cli\u003eAn effective alternative where gravers cannot be used\u003c\/li\u003e\n\u003cli\u003eMounted on a 3\/32 in. shank and sold by the piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\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\u003eBAU118.246\u003c\/td\u003e\n\u003ctd\u003e0.60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.247\u003c\/td\u003e\n\u003ctd\u003e0.70 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.248\u003c\/td\u003e\n\u003ctd\u003e0.80 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.249\u003c\/td\u003e\n\u003ctd\u003e0.90 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.250\u003c\/td\u003e\n\u003ctd\u003e1.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.252\u003c\/td\u003e\n\u003ctd\u003e1.20 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.254\u003c\/td\u003e\n\u003ctd\u003e1.40 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.256\u003c\/td\u003e\n\u003ctd\u003e1.60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.258\u003c\/td\u003e\n\u003ctd\u003e1.80 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.263\u003c\/td\u003e\n\u003ctd\u003e2.30 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Busch Burs","offers":[{"title":"0.60mm","offer_id":47090480218326,"sku":"BAU118.246","price":9.7,"currency_code":"USD","in_stock":true},{"title":"0.70mm","offer_id":47090480251094,"sku":"BAU118.247","price":9.7,"currency_code":"USD","in_stock":true},{"title":"0.80mm","offer_id":47090480283862,"sku":"BAU118.248","price":9.7,"currency_code":"USD","in_stock":true},{"title":"0.90mm","offer_id":47090480316630,"sku":"BAU118.249","price":9.7,"currency_code":"USD","in_stock":true},{"title":"1.00mm","offer_id":47090480349398,"sku":"BAU118.250","price":9.7,"currency_code":"USD","in_stock":true},{"title":"1.20mm","offer_id":47090480382166,"sku":"BAU118.252","price":9.7,"currency_code":"USD","in_stock":true},{"title":"1.40mm","offer_id":47090480414934,"sku":"BAU118.254","price":9.7,"currency_code":"USD","in_stock":true},{"title":"1.60mm","offer_id":47090480447702,"sku":"BAU118.256","price":9.7,"currency_code":"USD","in_stock":true},{"title":"1.80mm","offer_id":47090480480470,"sku":"BAU118.258","price":9.7,"currency_code":"USD","in_stock":true},{"title":"2.30mm","offer_id":47090480513238,"sku":"BAU118.263","price":9.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/BAU118.245_thumb_f87caaeb-cdbb-45e7-bbe5-f3515fe2c917.jpg?v=1753718406","url":"https:\/\/www.ottofrei.com\/it\/products\/busch-fig-2k-au-carbide-setting-burs-3-32-shank-0-60mm-2-30mm","provider":"Otto Frei","version":"1.0","type":"link"}
