Achieve chatter-free bearing cuts, exact pavilion seating, and vibration-free rotary milling with the authentic NIQUA SUPER Q® Stone-Setting Bur Assortment “Q(f) 1237”. Manufactured to strict Swiss precision standards from high-grade hardened tool steel, this comprehensive workshop assortment is specifically engineered for professional diamond setters, goldsmiths, and high-volume jewelry manufacturing ateliers.

Featuring a dedicated stone-setting profile with a conical 90° pavilion taper and straight vertical perimeter flutes (Figure Q / US: 413), the Series “Q(f) 1237″ shapes seats that match modern faceted round gemstones. The fine-cut cutting geometry delivers controlled, uniform material removal across soft precious metals like yellow gold, white gold, and fine silver, as well as brass, copper, and bronze, preventing gouging, prong distortion, or edge grab. Fitted with standardized 2.35 mm (3/32”) shanks, each bur runs true in jewelry micromotors, flexible shaft handpieces, and quick-change bench systems across 24 graduated sizes ranging from 0.90 mm to 4.40 mm.

Key Features & Benefits

• Dedicated Stone-Setting Geometry: Conical pavilion angle with straight side teeth forms crisp bearing ledges and level stone seats in one stroke.

• High-Grade Hardened Tool Steel: Tough alloy composition ensures sharp edge retention, high wear resistance, and long service life during repetitive bench runs.

• Micro-Graduated Size Progression: Spans 24 precise diameters from 0.90 mm up to 4.40 mm to match calibrated round stones, melee diamonds, and accent gems without gaps.

• Smooth, Low-Vibration Operation: Swiss concentric machining eliminates rotary chatter, ensuring level stone positioning and preventing prongs from snapping.

• Clean Material Removal: Fine-cut flutes slice smoothly through soft precious metals without surface dragging, minimizing hand clean-up and seat adjustment time.

• Standard 2.35 mm (3/32”) Shank: Precision ground for concentric mounting across standard bench micromotors, rotary handpieces, and flexible shaft systems.
