Achieve efficient material removal, clean structural cuts, and reduced frictional heat with authentic NIQUA SUPER Q® Crown Cutter Burs Series “45” (Crown Plate Saw). Manufactured in Germany by NIQUA with over 125 years of precision toolmaking heritage, this specialized rotary crown cutter is engineered specifically for professional goldsmiths, fine jewelry manufacturers, and precision metal engravers.
Featuring a distinctive crown-shaped cutting head with perimeter flutes, the Series “45” provides uniform material evacuation across planar metal surfaces, intricate recesses, and delicate workpiece sections. The crown design enhances chip clearance while minimizing thermal buildup during continuous high-speed rotary passes on gold, silver, copper, and brass. Fitted with a standard 2.35 mm (3/32”) shank, it integrates seamlessly into standard jewelry micromotors, flexible shaft handpieces, and quick-change chuck systems across diameters from 2.30 mm (45-023) up to 4.00 mm (45-040).
Key Features & Benefits
