Precision in contouring – designed for fine setting and engraving work
The NIQUA SUPER Q® tool steel cone burs “24” are specifically developed for precise and controlled work on soft precious metals and alloys. Their conical shape allows accurate machining of inner contours, recesses and transitions – wherever defined geometry and clean lines are essential.
In jewellery manufacturing, this cone shape is primarily used for preparing and refining stone seats, adjusting settings, and executing fine engraving or modelling work. The tapered geometry enables controlled material removal – from pinpoint accuracy to smooth transitions. This is particularly important when opening settings or refining delicate structures.
Manufactured from premium hardened tool steel, NIQUA SUPER Q® burs offer excellent durability, smooth running performance and consistent cutting efficiency even at high speeds. They are ideal for gold, silver, copper, brass and similar soft alloys that tend to clog tools.
With more than 125 years of experience, NIQUA develops precision tools trusted by professional goldsmiths and stone setters worldwide.
