Niqua® Q(f) Tool Steel Burs Stone Setting

Mill precision-calibrated bearing seats for round faceted stones, shape clean pavilion angles, and secure gemstones with exact fit and finish. Manufactured to Swiss precision standards for NIQUA, the NIQUA® SUPER Q® Q(f) Stone Setting Bur (Steinfasserfräser) is an essential rotary tool engineered for professional diamond setters, fine goldsmiths, and high-end jewelry manufacturers.

Featuring a dedicated stone setting geometry that pairs an angled conical tip with a straight cylindrical shoulder and a fine-cut (f) tooth pattern, this bur cuts a profiled seat that matches standard faceted gemstones. The conical point machines the pavilion recess while the straight side teeth true the girdle bearing shelf in a single pass, ensuring stones sit level and secure without shifting. Machined from premium hardened tool steel, each bur delivers clean chip clearance and smooth, vibration-free operation in ductile alloys including yellow gold, sterling silver, copper, and brass. Fitted with an industry-standard 2.35 mm (3/32") shank, these stone setting burs drop directly into jeweler flexible shaft handpieces, precision micromotors, and quick-change bench systems. Offered in calibrated diameters from 0.90 mm to 2.50 mm (Item No. 03 227 009 to 03 227 025), each size is packaged in a bench storage box containing 6 pieces.

Clean Concentric Operation: Precision-ground Swiss tool steel shank eliminates radial wobble, allowing steady handpiece tracking under the microscope.
Clog-Resistant Chip Clearance: Optimized flute gullets clear swarf rapidly, preventing metal galling and tooth loading during repetitive pave and prong work.
Hardened Swiss-Quality Tool Steel: Formulated for durable edge retention and wear resistance during demanding stone setting production.
Universal 2.35 mm (3/32") Shank: Provides seamless compatibility across all standard flexible shafts, quick-change handpieces, and laboratory micromotors.
