Efficient material removal and smooth operation – designed for optimal chip evacuation
The NIQUA SUPER Q® helical cylinder burs “29” are engineered for controlled and consistent machining of soft precious metals. The cylindrical shape combined with spiral cutting edges ensures continuous cutting action and significantly improved chip removal.
In jewellery making and stone setting, this bur shape is ideal for efficient surface work and uniform material removal. The helical geometry prevents clogging and reduces vibration – a key advantage when working with ductile metals such as gold and silver.
The cylindrical form allows precise guidance on flat surfaces, while the spiral cutting edges ensure a smooth engagement with the material, resulting in clean finishes and high process reliability.
Manufactured from premium hardened tool steel, NIQUA SUPER Q® burs provide long service life, smooth operation and consistent cutting performance even at high speeds. They are 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.
