Precision in depth – designed for detailed work with optimal chip evacuation
The NIQUA SUPER Q® tapered helical burs “31” combine excellent accessibility with efficient chip removal. The tapered shape together with spiral cutting edges ensures smooth, controlled cutting even in hard-to-reach areas.
In jewellery making and stone setting, this bur is ideal for detailed work such as refining settings, working internal contours and removing material in deeper sections. The tapered geometry improves visibility and control, while the helical cutting edges reduce clogging and ensure a smooth cutting action.
This makes the bur particularly suitable for delicate work where precision and control are essential.
Manufactured from premium hardened tool steel, NIQUA SUPER Q® burs offer long service life, smooth operation and consistent cutting performance even at high speeds. Ideal for gold, silver, copper, brass and similar soft alloys.
With over 125 years of experience, NIQUA stands for precision tools trusted by professionals worldwide.
