Achieve uniform surface leveling, clean right-angle grooves, and vibration-free rotary milling with authentic NIQUA SUPER Q® Cylinder Burs Series “R(f)”. Manufactured from premium hardened tool steel in genuine Swiss precision quality, this rotary bur series is engineered specifically for professional goldsmiths, fine engravers, and precision jewelry manufacturing workshops.
Featuring a parallel cylindrical body paired with a fine-cut (f) fluting pattern and a radially cut flat end face, the Series “R(f)” provides controlled material removal across planar metal surfaces, straight channels, and defined slots. The fine tooth geometry cuts smoothly across soft precious metals—such as gold and silver—as well as copper, brass, and related alloys without grabbing or chattering. 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 1.00 mm (03 228 010) up to 6.00 mm (03 228 060).
Key Features & Benefits
-
Cylindrical Milling Geometry: Parallel side flutes and flat end face machine clean horizontal planes, straight slots, and uniform grooves without gouging.
-
Fine Cut (f) Tooth Configuration: Densely spaced fine teeth deliver smooth, controlled material removal, producing homogeneous surface finishes 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, pavé channels, and thin bezels from distortion.
-
Swiss Precision Quality: Built under Swiss precision standards to ensure consistent dimensional accuracy for fine metalworking.
-
Standard 2.35 mm (3/32”) Shank: Precision ground to ensure universal fitment across standard bench micromotors, rotary handpieces, and flexible shaft systems.
