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

Setting stones in hard metals such as platinum, titanium, white gold, and steel calls for a full range of bur shapes and sizes at the bench, from the starter hole through the finished seat. The BURRO Ultimate Busch Carbide Stonesetters 85-Piece Burs & Drills Kit from Nashef Designs brings together six complete sets of Busch carbide burs and drills, spanning round burs, pave cut burs, hart burs, setting burs, and short twist drills, along with the BURRO Jeweler's Bur Rotating Organizing Holder. Together these tools cover every critical step of pave, flush, and bezel stone setting.

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, which makes them a cost-efficient choice for high-volume professional use. Every bur and drill shank in the kit is 3/32". Recommended operating speed is 2,000–10,000 RPM for the burs and 3,000–5,000 RPM for the short twist drills.

The BURRO Rotating Organizer (128.508) anchors the kit with seven layers marked with Busch bur part numbers for rapid identification, all mounted on a smooth-action lazy Susan for effortless bench-side rotation. The base layer holds up to 47 round and ball bur compartments, and the top layer adds 20 extra 3/32" holes plus 14 GRS quick-change slots. It is 3D printed by Nashef Designs and measures 9" H × 8" W × 8" D.
