{"product_id":"busch-5120-carbide-pave-setting-bur-kit-12pc","title":"Busch 5120 Carbide Pave Setting Bur Kit","description":"\u003cp\u003eMicrosetting in hard metal alloys like 18k white gold eats through regular tungsten vanadium burs quickly — and cutting steel or titanium with standard burs is virtually impossible. Busch developed the 5120 Carbide Pavé Setting Bur Kit specifically to handle these demanding materials. The carbide construction stays sharp longer and cuts cleaner, delivering outstanding results where conventional burs fall short. This kit contains the essential bur types needed to complete the full pavé setting sequence on hard metals, including steel, platinum, titanium, and hard alloys of gold and silver.\u003c\/p\u003e\u003cp\u003eThe three-step pavé workflow is built into the kit's composition: begin by drilling starter holes with the short carbide twist drills, open and shape the stone seats with the carbide ball burs, then form the prongs and separate the settings using the miniature carbide circular saws. Each bur type is represented in the sizes most commonly needed for pavé work, making this kit a practical starting point for setters working in challenging alloys.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCarbide construction stays sharp longer than tungsten vanadium burs in hard metals\u003c\/li\u003e\n\u003cli\u003eCuts cleanly in steel, platinum, titanium, and hard gold and silver alloys\u003c\/li\u003e\n\u003cli\u003eComplete three-step pavé workflow: drill, seat, and separate\/form prongs\u003c\/li\u003e\n\u003cli\u003eIncludes four twist drill sizes, six ball bur sizes, and two circular saw sizes\u003c\/li\u003e\n\u003cli\u003eShort carbide twist drills (Fig 4205S) for precise starter holes\u003c\/li\u003e\n\u003cli\u003eRound carbide ball burs (Fig 1AU) for opening and shaping stone seats\u003c\/li\u003e\n\u003cli\u003eCarbide circular saws (Fig 231F and 231FL) in two kerf widths for prong forming and setting separation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eKit Reference\u003c\/th\u003e\n\u003ctd\u003eBusch 5120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBur Material\u003c\/th\u003e\n\u003ctd\u003eCarbide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRecommended Applications\u003c\/th\u003e\n\u003ctd\u003eSteel, platinum, titanium, hard gold alloys, hard silver alloys\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal Pieces\u003c\/th\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTwist Drill Sizes\u003c\/th\u003e\n\u003ctd\u003e0.7mm, 0.8mm, 0.9mm, 1.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBall Bur Sizes\u003c\/th\u003e\n\u003ctd\u003e1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCircular Saw Sizes\u003c\/th\u003e\n\u003ctd\u003e2.3mm × 0.2mm (Fig 231F), 2.3mm × 0.3mm (Fig 231FL)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBAU128.407 – Busch Short Carbide Twist Drill Fig 4205S, 0.7mm\u003c\/li\u003e\n\u003cli\u003eBAU128.408 – Busch Short Carbide Twist Drill Fig 4205S, 0.8mm\u003c\/li\u003e\n\u003cli\u003eBAU128.409 – Busch Short Carbide Twist Drill Fig 4205S, 0.9mm\u003c\/li\u003e\n\u003cli\u003eBAU128.410 – Busch Short Carbide Twist Drill Fig 4205S, 1.0mm\u003c\/li\u003e\n\u003cli\u003eBAU118.180 – Busch Round Carbide Ball Bur Fig 1AU, 1.0mm\u003c\/li\u003e\n\u003cli\u003eBAU118.182 – Busch Round Carbide Ball Bur Fig 1AU, 1.2mm\u003c\/li\u003e\n\u003cli\u003eBAU118.184 – Busch Round Carbide Ball Bur Fig 1AU, 1.4mm\u003c\/li\u003e\n\u003cli\u003eBAU118.186 – Busch Round Carbide Ball Bur Fig 1AU, 1.6mm\u003c\/li\u003e\n\u003cli\u003eBAU118.188 – Busch Round Carbide Ball Bur Fig 1AU, 1.8mm\u003c\/li\u003e\n\u003cli\u003eBAU118.192 – Busch Round Carbide Ball Bur Fig 1AU, 2.2mm\u003c\/li\u003e\n\u003cli\u003eBAU118.231 – Busch Carbide Circular Saw Fig 231F, 2.3mm × 0.2mm\u003c\/li\u003e\n\u003cli\u003eBAU118.232 – Busch Carbide Circular Saw Fig 231FL, 2.3mm × 0.3mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Busch Burs","offers":[{"title":"Default Title","offer_id":43579647230166,"sku":"BC118.170","price":160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/busch-5120-carbide-pave-setting-bur-kit-otto-frei.jpg?v=1719958520","url":"https:\/\/www.ottofrei.com\/products\/busch-5120-carbide-pave-setting-bur-kit-12pc","provider":"Otto Frei","version":"1.0","type":"link"}
