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® Hollow Bur "S(f)" is a specialised precision rotary tool developed for professional jewellers, stone setters, engravers, and jewellery manufacturers. Hollow burs are essential for applications requiring controlled hollowing, recessing, shaping, and detailed finishing, making them ideal for stone setting preparation, cavity creation, engraving, and intricate jewellery work.
Designed specifically for demanding jewellery applications, the SUPER Q® S(f) Hollow Bur enables clean, precise, and consistent machining of soft precious metals such as gold and silver, as well as copper, brass, and other non-ferrous alloys.
Its advanced hollow-cut geometry provides highly accurate material removal while ensuring excellent chip evacuation. This minimises clogging, improves cutting efficiency, and maintains smooth performance even at higher rotational speeds. The result is exceptional surface quality, precise contours, and maximum control during delicate operations.
Manufactured from premium hardened tool steel, the bur offers outstanding durability, extended tool life, and smooth low-vibration operation. As part of the renowned NIQUA SUPER Q® Swiss precision tool range, it delivers the reliability and accuracy required by professional jewellery workshops worldwide.
