Achieve true horizontal bearing planes, precise edge refining, and controlled surface leveling with authentic NIQUA SUPER Q® Wheel Burs Series “25”. Manufactured in Germany by NIQUA with over 125 years of specialized toolmaking heritage, this rotary wheel bur is engineered specifically for professional goldsmiths, diamond setters, and fine jewelry manufacturing workshops.
Featuring a distinct flat-topped wheel profile with radial cutting flutes, the Series “25” allows controlled material removal on planar areas, bearing shoulders, and channel walls across gold, silver, copper, and brass. The flat cutting face levels stone seats without altering surrounding collet geometry, preventing unwanted gouging. Fitted with a standard 2.35 mm (3/32”) shank, it integrates seamlessly into jewelry micromotors and flex shaft handpieces across diameters from 0.60 mm (25-006) up to 2.90 mm (25-029).
Key Features & Benefits
-
Dedicated Wheel Cutting Profile: Flat top with sharp circumferential cutting flutes creates uniform horizontal floors and crisp right-angle steps in setting seats.
-
Hardened Tool Steel Construction: Premium German tool steel delivers wear resistance, smooth rotary cutting, and long service life during daily bench use.
-
Smooth, Low-Vibration Operation: High concentric accuracy prevents tool runout and chatter marks, protecting thin bezel borders and prongs from distortion.
-
Clog-Resistant Rotary Action: Flute geometry evacuates metal chips cleanly, preventing clogging when milling softer precious metals like fine gold and silver.
-
Standard 2.35 mm (3/32”) Shank: Precision ground to fit all standard micromotor chucks, flexible shaft handpieces, and quick-change systems.
