Niqua® Y(f) Tool Steel Burs Wheel

Mill precision grooves, define clean edges, and machine flat surfaces with smooth rotary tracking and low vibration. Manufactured to Swiss-Made precision standards for NIQUA, the NIQUA® SUPER Q® Wheel Bur "Y(f)" is an essential rotary tool engineered for professional goldsmiths, diamond setters, hand engravers, and precision metal fabricators.

Featuring a specialized wheel-shaped geometry with radial end-cutting flutes across the top and bottom faces joined by circumferential cutting teeth, the Series Y(f) bur allows artisans to cut straight tracks, true bearing edges, and level flat surfaces without wandering. Its fine-cut tooth pattern (f) ensures smooth cutting action, controlled material removal, and clean surface finishes in soft, ductile alloys including yellow gold, sterling silver, platinum, copper, brass, and related non-ferrous metals. Machined from premium hardened tool steel, each bur maintains dependable edge retention and uniform chip clearance during high-speed bench production. Built with a standard 2.35 mm (3/32") shank, these wheel burs fit directly into jeweler flexible shaft handpieces, precision micromotors, and quick-change bench systems. Offered in calibrated diameters of 1.50 mm, 2.00 mm, and 2.50 mm (Item Numbers: 03 231 015 to 03 231 025), each size is packaged in a bench storage box containing 6 pieces.

Why Choose NIQUA® SUPER Q® Y(f) Wheel Burs

• Distinctive Wheel-Shaped Profile: Flat faces combined with sharp circumferential cutting teeth allow precise machining of channels, slots, edges, and flat surfaces.

• Fine Cut (f) Tooth Architecture: Closer, finer-fluted teeth deliver controlled stock removal and smooth surface finishes, preventing aggressive grabbing or chatter in soft precious metals.

• Controlled Depth Guidance: The flat face acts as a natural stabilizer against horizontal planes, eliminating tool wander during recess flattening.

• Low-Vibration Concentric Operation: Precision-ground tool steel core minimizes radial runout, ensuring steady handpiece tracking under high bench magnification.

• Clog-Resistant Chip Clearance: Optimized tooth gullets clear swarf rapidly, preventing metal galling and tooth buildup in soft gold and silver alloys.

• Hardened Swiss-Quality Tool Steel: Provides wear resistance and consistent cutting efficiency across daily workshop production.

• Universal 2.35 mm (3/32") Shank: Provides seamless compatibility across all standard flexible shaft systems, quick-change handpieces, and laboratory micromotors.
