Achieve smooth domed prong tips, controlled recessing, and uniform hollow contours with authentic NIQUA SUPER Q® Cup / Hollow Burs Series “S(f)”. Manufactured from premium hardened tool steel in genuine Swiss precision quality, this rotary bur series is engineered specifically for professional goldsmiths, diamond setters, and fine jewelry manufacturing ateliers.
Featuring an inverted concave cup profile paired with a fine-cut (f) internal fluting geometry, the Series “S(f)” provides controlled material removal across prong heads, rivet ends, and curved metal hollows. The internal radial teeth round wire ends into smooth hemispherical domes without flattening prongs or marking adjacent gemstone crowns. Fitted with a standardized 2.35 mm (3/32”) shank, it integrates into standard jewelry micromotors, flexible shaft handpieces, and quick-change bench systems across diameters from 0.80 mm (03 230 008) to 6.00 mm (03 230 060).
Key Features & Benefits
-
Concave Cup / Hollow Cutting Geometry: Interior hemispherical fluting rounds off prong ends, bead settings, and wire rivets into uniform domes.
-
Fine Cut (f) Internal Toothed Fluting: Close-spaced teeth shave metal smoothly in micro-increments, preventing aggressive grabs on ductile precious alloys.
-
Hardened Premium Tool Steel: Tough 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 and thin bezels from distortion.
-
Swiss Precision Quality: Built under Swiss precision standards to ensure consistent dimensional accuracy across all ISO sizes.
-
Standard 2.35 mm (3/32”) Shank: Precision ground to ensure universal fitment across standard bench micromotors, rotary handpieces, and flexible shaft systems.
