Achieve controlled curved shaping, refined hollow transitions, and vibration-free rotary metalworking with authentic NIQUA SUPER Q® Flame Burs Series “81”. Manufactured from premium hardened tool steel in genuine Swiss precision quality, this large-diameter rotary bur series is engineered specifically for professional goldsmiths, fine engravers, and precision jewelry manufacturing workshops.

Featuring an ogival flame-shaped profile with longitudinally ground cutting flutes that taper into a slender domed tip, the Series “81” provides versatile cutting control across concave hollows, interior ring curves, and organic transitions. The sweeping curved flanks cut smoothly across soft precious metals like yellow gold and silver, as well as copper, brass, and related non-ferrous alloys without grabbing or gouging. Fitted with a standardized 2.35 mm (3/32”) shank, it integrates seamlessly into standard jewelry micromotors, flexible shaft handpieces, and quick-change bench systems across diameters from 5.00 mm (03 241 050) up to 8.00 mm (03 241 080).

 

Key Features & Benefits

  • Specialized Flame Cutting Geometry: Ogival tapered profile allows both side-flank contour blending and controlled point detailing in confined hollows.

  • Hardened High-Grade Tool Steel: Robust alloy composition provides high wear resistance and extended edge sharpness throughout daily workshop use.

  • Smooth, Low-Vibration Operation: High concentricity reduces runout and vibration, protecting delicate prongs, pavé channels, and thin bezels from distortion.

  • Clean, Controlled Material Removal: Finely pitched teeth slice through soft precious metals, preventing metal dragging and reducing subsequent polishing stages.

  • Swiss Precision Quality: Built under strict Swiss manufacturing standards to ensure consistent dimensional accuracy across large bur head sizes.

  • Standard 2.35 mm (3/32”) Shank: Precision ground to ensure universal compatibility with standard bench micromotors, rotary handpieces, and flexible shaft systems.

 

Primary Application Sectors

  • Interior Shank Shaping, Gallery Hollowing & Sculptural Goldsmithing

  • Blending Transitions on Cast Mountings, Pendants, and Bangles

  • Decorative Metal Engraving, Relief Detailing & Edge Refinement

  • Controlled Low-Speed Finishing on Gold, Silver, Brass, and Copper
