Microsetting in hard metal alloys like 18k white gold wears 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\u003e12 pieces: four twist drill sizes, six ball bur sizes, and two circular saw sizes\u003c\/li\u003e\n\u003cli\u003eShort carbide twist drills (Fig 4205S) in 0.7mm, 0.8mm, 0.9mm, and 1.0mm for precise starter holes\u003c\/li\u003e\n\u003cli\u003eRound carbide ball burs (Fig 1AU) in 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, and 2.2mm 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","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\/it\/products\/busch-5120-carbide-pave-setting-bur-kit-12pc","provider":"Otto Frei","version":"1.0","type":"link"}
