Spanning sizes from 0.90mm to 3.00mm, this set is engineered for precision stone setting and metal preparation work across a broad spectrum of gem sizes. Each bur is machine-made to ultra-high precision tolerances, producing uniform geometry that cuts precious metal smoothly and cleanly — with no chatter or drag. Tungsten Vanadium cup burs are among the most popular burs used throughout the professional jewelry industry, and this kit represents an efficient way to stock your bench with a complete working range.\u003c\/p\u003e\u003cp\u003eUnlike High Speed Steel (HSS) burs, which are individually hand-cut and may vary slightly from piece to piece, Tungsten Vanadium burs are machine-manufactured for consistent, repeatable performance across every size in the set. While HSS burs offer greater longevity, Tungsten Vanadium burs deliver exceptional precision at a more accessible price point — making them a staple choice for production jewelers and bench craftspeople alike.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSet of 12 Swiss-made Tungsten Vanadium cup burs\u003c\/li\u003e\n\u003cli\u003eSize range: 0.90mm – 3.00mm across 12 incremental sizes\u003c\/li\u003e\n\u003cli\u003eMachine-made to ultra-high precision tolerances for uniform, consistent geometry\u003c\/li\u003e\n\u003cli\u003eCuts precious metal smoothly and cleanly with no chatter or drag\u003c\/li\u003e\n\u003cli\u003e3\/32\" diameter shafts standard across all burs in the set\u003c\/li\u003e\n\u003cli\u003eIncludes a round plastic holder for organized bench storage\u003c\/li\u003e\n\u003cli\u003eTungsten Vanadium steel construction — cost-effective alternative to HSS burs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBur Type\u003c\/th\u003e\n\u003ctd\u003eCup Bur\u003c\/td\u003e\n\u003c\/tr\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\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\u003e0.90mm – 3.00mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePieces Included\u003c\/th\u003e\n\u003ctd\u003e12 burs + 1 round plastic holder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e118.400 – Cup Bur 0.90mm\u003c\/li\u003e\n\u003cli\u003e118.401 – Cup Bur 1.00mm\u003c\/li\u003e\n\u003cli\u003e118.402 – Cup Bur 1.20mm\u003c\/li\u003e\n\u003cli\u003e118.403 – Cup Bur 1.40mm\u003c\/li\u003e\n\u003cli\u003e118.404 – Cup Bur 1.50mm\u003c\/li\u003e\n\u003cli\u003e118.405 – Cup Bur 1.60mm\u003c\/li\u003e\n\u003cli\u003e118.406 – Cup Bur 1.80mm\u003c\/li\u003e\n\u003cli\u003e118.407 – Cup Bur 2.10mm\u003c\/li\u003e\n\u003cli\u003e118.408 – Cup Bur 2.30mm\u003c\/li\u003e\n\u003cli\u003e118.409 – Cup Bur 2.50mm\u003c\/li\u003e\n\u003cli\u003e118.410 – Cup Bur 2.70mm\u003c\/li\u003e\n\u003cli\u003e118.412 – Cup Bur 3.00mm\u003c\/li\u003e\n\u003cli\u003e119.248 – Round Plastic Holder\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei Swiss Burs","offers":[{"title":"Default Title","offer_id":43582563647702,"sku":"118.008","price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/swiss-cup-bur-kit-12-pieces-0-90mm-to-3-00mm-otto-frei.jpg?v=1719956982","url":"https:\/\/www.ottofrei.com\/products\/swiss-cup-bur-kit-12-piece-0-90mm-3-00mm-tungsten-vanadium","provider":"Otto Frei","version":"1.0","type":"link"}
