Niqua® 52 SUPER-Q Wax Burs

Carve crisp contours, mill intricate reliefs, and remove bulk material from carving wax without heat buildup, melting, or chip binding. Engineered specifically for professional model makers, jewelry designers, and lost-wax casting artisans, the NIQUA® SUPER Q® Series "52" Helix Wax Bur is a specialized rotary carving tool manufactured to exacting Swiss-Made precision standards. 

Featuring a distinct two-flute helical geometry with deep chip relief channels and positive rake cutting edges, the Series 52 bur cleanly shears modeling wax instead of friction-rubbing it. Standard multi-flute metal burs quickly clog with melted wax swarf, but the open helix profile of the 52 bur continuously expels shaved wax ribbons away from the cutting tip, maintaining smooth, low-vibration operation even at high rotational speeds. Machined from hardened high-grade tool steel, these burs hold razor-sharp cutting edges over long production cycles across hard injection waxes, purple and green carving wax blocks, ring tubes, and milling waxes. Fitted with an industry-standard 2.35 mm (3/32") shank, they integrate directly into flexible shaft handpieces, precision bench micromotors, and quick-change systems. Available in calibrated diameters of 1.60 mm and 2.30 mm (Art.-Nr. 03 233 016 and 03 223 023), each size is packaged in a bench storage box containing 6 pieces.

Why Choose NIQUA® SUPER Q® 52 Helix Wax Burs

• Specialized Two-Flute Helix Geometry: Deep spiral flutes channel shaved wax out of deep cavities instantly, preventing clogging, surface gumming, and friction-induced melting. 

• Clean Shearing Action: Sharp, precision-ground tool steel edges slice through modeling wax blocks smoothly without grabbing, chattering, or chipping delicate thin-walled designs. 

• True Concentric Swiss Machining: Precision-ground tool steel shanks reduce radial runout, ensuring steady handpiece tracking under high bench magnification. 

• Minimal Friction Heat Generation: Generous chip gullets prevent heat transfer to the wax model, preserving fine filigree edges and dimensional fidelity during high-speed passes. 

• Hardened Swiss-Quality Tool Steel: Provides edge sharpness and wear resistance during daily wax carving and prototyping workflows. 

• Universal 2.35 mm (3/32") Shank: Drops into standard jewelry flex shaft handpieces and micromotor quick-change collets without requiring collet adapters.
