Achieve smooth domed prong heads, controlled cavity hollowing, and clog-free rotary cutting with authentic NIQUA SUPER Q® Cup Burs Series “2C1”. Representing an advanced generation of precision rotary burs engineered specifically for professional goldsmiths, diamond setters, and high-volume jewelry manufacturing workshops, the Series “2C1” introduces an integrated chip evacuation slot directly across the cutting cup.
Featuring an extra-deep, super-thin cup wall profile paired with cross-cutting chip escape channels, the Series “2C1” continuously ejects metal swarf away from the working zone during operation. This prevents tool clogging, frictional heat buildup, and surface galling when machining soft, ductile precious metals like yellow gold, fine silver, copper, and brass. Manufactured from premium hardened tool steel, it delivers consistent cutting efficiency, vibration-free rotary stability, and extended service life across elevated bench speeds. 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 0.80 mm (03 237 008) to 2.30 mm (03 237 023).
Key Features & Benefits
-
Integrated Chip Evacuation Slot: Dual cross-slots allow chips to evacuate continuously, preventing soft gold and silver shavings from packing inside the cup.
-
Super-Thin & Extra-Deep Cup Walls: Slender outer perimeter provides enhanced clearance between tightly packed stones in pavé and cluster settings, avoiding facet scratches.
-
Hardened High-Quality Tool Steel: Precision alloy treatment delivers high wear resistance and extended edge sharpness throughout demanding daily bench use.
-
Smooth, Low-Vibration Operation: Concentric rotary tracking prevents tool hop, ensuring prong tips and wire ends are rounded into symmetrical hemispherical domes.
-
German Precision Quality: Engineered to rigorous European standards within the NIQUA SUPER Q® series for consistent dimensional accuracy.
-
Standard 2.35 mm (3/32”) Shank: Precision ground to ensure universal compatibility with standard bench micromotors, rotary handpieces, and flexible shaft systems.
