BURRO Ultimate Busch Carbide Stonesetters 85-Piece Burs & Drills Kit

The BURRO Ultimate Busch Carbide Stonesetters 85-Piece Burs & Drills Kit is a comprehensive stone-setting toolkit assembled for professional jewelers who demand precision, durability, and organization. This all-in-one kit pairs six complete sets of Busch carbide burs and drills — spanning round burs, hart burs, setting burs, pave-cut burs, and short twist drills — with the BURRO Jeweler's Bur Rotating Organizing Holder from Nashef Designs. Together, these tools cover every critical step of pave, flush, and bezel stone setting in hard metals including platinum, titanium, white gold, and steel.

Busch carbide burs are manufactured in Germany using hot isostatically compressed finest-grain carbide and state-of-the-art blade geometry. They outlast tungsten vanadium and high-speed steel burs, making them a cost-efficient choice for high-volume professional use. All bur and drill shanks are 3/32". Recommended operating speed is 2,000–10,000 RPM for burs; 3,000–5,000 RPM for the short twist drills.

The BURRO Rotating Organizer (128.508) anchors the kit with a 7-layer, lazy Susan–mounted holder marked with Busch bur part numbers for rapid identification and access. It accommodates virtually all 3/32" shank bur styles and is 3D printed by Nashef Designs. Dimensions: 9" H × 8" W × 8" D.
