NIQUA manufactures precision tools for goldsmiths, stone setters and jewellery makers. Professionals in more than 140 countries trust tools made in Germany and Switzerland.
The NIQUA SUPER Q® Extended Cylinder Bur "RR(f)" is a premium precision rotary tool designed for professional jewellery manufacturing, engraving, and fine metalworking applications. Manufactured from high-quality hardened tool steel, this bur is ideal for machining soft precious metals such as gold and silver, as well as copper, brass, and other soft alloys.
Its extended cylindrical shape provides improved reach and control when working in deeper grooves, slots, flat surfaces, and straight contours. The fine-cut tooth geometry (f) ensures smooth cutting action, precise material removal, and excellent surface finishes. The longer working head makes this bur particularly suitable for detailed jewellery work where accessibility and accuracy are essential.
Built from hardened tool steel, the RR(f) bur offers excellent wear resistance, low-vibration operation, and consistent cutting performance even at higher rotational speeds. The result is clean, accurate workmanship and reliable professional results.
As part of the renowned NIQUA SUPER Q® Swiss precision tool range, the RR(f) Extended Cylinder Bur is trusted by jewellers and craftsmen who demand outstanding precision, durability, and quality.
