Achieve precise seat milling, controlled material removal, and chatter-free rotary cutting with authentic NIQUA SUPER Q® Round Ball Burs Series “23”. Precision-manufactured in Germany from premium hardened tool steel, this universal rotary ball bur series is engineered specifically for professional goldsmiths, diamond setters, and jewelry manufacturing facilities.
Featuring a precisely ground spherical fluted head, the Series “23” ball bur delivers smooth, clean cutting action with high concentric accuracy across gold, silver, and non-ferrous metals. Its optimized flute geometry promotes efficient chip evacuation, preventing clogging when milling softer precious alloys. Fitted with a standard 2.35 mm (3/32”) shank, it integrates seamlessly into standard micromotors, flex shaft handpieces, and bench rotary systems across sizes ranging from 23-003 (0.3 mm) up to 23-100 (10.0 mm).
Key Features & Benefits
-
Precisely Ground Spherical Head: Fluted ball geometry ensures concentric rotation and uniform surface cutting, eliminating tool wander during delicate stone seat preparation.
-
Optimized Chip Evacuation: Engineered flute spacing prevents metal clogging and overheating when milling ductile gold, fine silver, and brass alloys.
-
Hardened Tool Steel Construction: Premium tool steel composition provides wear resistance and consistent cutting edge sharpness throughout daily workshop use.
-
High Concentric Accuracy: Tight manufacturing tolerances eliminate vibration and runout, protecting thin prong walls and bezel borders from distortion.
-
Standard 2.35 mm (3/32”) Shank: Compatible with standard jewelry micromotor handpieces, flexible shaft units, and rotary quick-change chucks.
-
Extensive Size Range: Available in a continuous progression from micro-drilling diameters up to large bearing sizes (Series 23-003 through 23-100).
