Technical Specifications

Model & Size Dimension Matrix

Achieve controlled spherical recessing, micro-pilot positioning, and vibration-free rotary milling with authentic NIQUA SUPER Q® Round Carbide Burs Series “123”. Manufactured to strict Swiss precision standards, this versatile rotary bur series is engineered specifically for demanding jewelry manufacturing, precision stone setting, fine engraving, and high-tolerance metalworking.

Featuring a precision-ground spherical (round/ball) cutting head with radial micro-fluting, the Series “123” provides smooth, multi-directional cutting control across delicate hollows, bead recesses, and setting layouts. The solid tungsten carbide construction retains sharp cutting edges far longer than conventional tool steel, cutting cleanly through precious metals like gold and silver as well as demanding hard materials including stainless steel, titanium, glass, and technical ceramics without edge breakdown. 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 micro-diameters from 0.20 mm (03 235 002) up to 2.70 mm (03 235 027).

Key Features & Benefits

• Spherical Ball Head Geometry: Ground into a true spherical radius for multi-directional engraving, channel clearing, and opening round gemstone seats.

• Solid Tungsten Carbide Construction: Delivers high wear resistance, rigidity, and thermal durability when machining abrasive, work-hardened, or dense materials.

• Micro-Grain Edge Retention: Precision cutting facets slice cleanly through hard metals without chipping, preventing premature tool wear.

• Smooth, Low-Vibration Operation: Concentric rotary tracking prevents bur chatter, protecting delicate prongs and thin bezel walls from distortion.

• Swiss Precision Quality: Built under strict Swiss manufacturing standards from the SUPER Q® series to ensure dimensional consistency across micro sizes.

• Standard 2.35 mm (3/32”) Shank: Precision ground to ensure universal compatibility with standard bench micromotors, rotary handpieces, and flexible shaft systems.

Primary Application Sectors
