Busch 5120 Carbide Pave Setting Bur Kit

Microsetting 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.

The 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.
