The NIQUA SUPER Q 45° Cone Bur NN(f) is a premium precision tool designed for machining soft precious metals such as gold and silver, as well as copper, brass, and other non-ferrous alloys. Its precisely engineered 45° cone profile, combined with a fine-cut tooth pattern (f), enables exceptionally accurate, clean, and controlled cutting. This makes it the perfect choice for engraving, countersinking, chamfering, and intricate detail work in professional jewellery manufacturing.

Manufactured from hardened tool steel, this bur offers outstanding wear resistance, smooth low-vibration operation, and consistent cutting performance, even at high rotational speeds. The result is superior dimensional accuracy, clean surface finishes, and consistently professional-quality workmanship.

The NIQUA SUPER Q NN(f) 45° Cone Bur is the ideal solution for jewellers, goldsmiths, engravers, and precision craftsmen who demand maximum accuracy, durability, and reliable performance. Tool steel burs are particularly suitable for working annealed precious metals and alloys that tend to clog conventional cutting tools.
