The NIQUA SUPER Q 45° Cone Bur NN(r) is a premium precision tool engineered for machining soft precious metals such as gold and silver, as well as copper, brass, and other non-ferrous alloys. Its accurately machined 45° cone profile, combined with a standard-cut tooth pattern (r), ensures clean, controlled, and consistent material removal, making it ideal for engraving, countersinking, chamfering, and intricate jewellery work.
Manufactured from hardened tool steel, this bur delivers exceptional wear resistance, smooth low-vibration operation, and reliable cutting performance even at high rotational speeds. The result is outstanding dimensional accuracy, clean surface finishes, and dependable process control for professional applications.
The NIQUA SUPER Q NN(r) 45° Cone Bur is the perfect choice for jewellers, goldsmiths, engravers, and precision craftsmen who require durability, accuracy, and consistently high-quality results.
