Carve delicate decorative lines, clear microscopic setting margins, and refine intricate jewelry contours with pinpoint accuracy and reduced rotational vibration. Manufactured to Swiss-Made standards for NIQUA, the NIQUA® SUPER Q® FK Krause Bur is an ultra-fine rotary finishing and engraving tool designed for master goldsmiths, diamond setters, and precision micro-mechanics.
Characterized by an elongated, spindle-shaped pointed profile with fine radial fluting and cross-cut serrations, the Krause bur geometry offers an optimal balance between needle-point accessibility and steady lateral cutting guidance. Forged from premium hardened tool steel, each bur retains a keen cutting edge while resisting galling and tool loading in gummy, ductile precious metals such as yellow gold, sterling silver, copper, brass, and related non-ferrous alloys. Mounted on a standard 2.35 mm (3/32") shank, these burs drop directly into jeweler flexible shaft handpieces, precision micromotors, and quick-change bench systems. Offered in precision-calibrated diameters of 1.00 mm and 1.20 mm (Art.-Nr. 03 214 010 and 03 214 012), each size is packaged in a bench storage box containing 6 pieces.
Why Choose NIQUA® SUPER Q® FK Krause Burs
-
Distinctive Krause Needle-Spindle Profile: Tapers gradually to a sharp tip, allowing the artisan to navigate deep, confined gallery walls, tight filigree junctions, and micro-claw intersections without obstructing visibility.
-
Simultaneous Point and Flank Cutting: Allows delicate tip engraving, channel scribing, and controlled lateral stock removal in a single fluid hand stroke.
-
Vibration-Reduced Concentric Operation: Precision-ground Swiss tool steel core minimizes radial runout, eliminating chatter marks under high bench magnification.
-
Clog-Resistant Chip Clearance: Optimized flute gullets quickly evacuate soft metal swarf, preserving sharp cutting action without overheating or burning delicate workpieces.
-
Hardened Swiss-Quality Tool Steel: Formulated for maximum edge retention, wear resistance, and long service life during high-speed production bench sessions.
-
Universal 2.35 mm (3/32") Shank: Provides seamless compatibility across all standard flexible shafts, quick-change handpieces, and laboratory micromotors.
