Achieve controlled internal shaping, seamless curved transitions, and vibration-free rotary metalworking with authentic NIQUA SUPER Q® Long Bud Burs Series “82”. Precision-manufactured from high-grade hardened tool steel to strict Swiss precision standards, this large-head rotary bur series is engineered specifically for professional goldsmiths, fine engravers, and jewelry manufacturing ateliers.
FFeaturing an elongated bud-shaped profile with a dome-rounded nose and longitudinal cutting flutes, the Series “82” provides steady, guided material removal across deep concave cavities, curved ring galleries, and organic sculptural surfaces. Its gently tapered profile distributes cutting contact smoothly across soft precious metals like yellow gold and silver, as well as copper, brass, and related non-ferrous alloys without gouging or chatter marks. 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 of 6.00 mm, 7.00 mm, and 8.00 mm.
Key Features & Benefits
-
Elongated Bud Cutting Geometry: Combines side-flank contour blending with a tapered nose for shaping curved cavities and concave hollows.
-
Hardened High-Grade Tool Steel: Robust alloy composition provides high wear resistance and extended edge sharpness throughout demanding daily bench 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: Precision-milled flutes slice smoothly through soft precious metals, preventing metal dragging and reducing subsequent polishing stages.
-
Swiss Precision Quality: Built under strict Swiss manufacturing standards from the NIQUA SUPER Q® series 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.
