1950 siaspeed - for a perfect finish at full speed

The versatile all-round product 1950 siaspeed is specially designed for high stock removal rates, perfect surface quality and long life in applications such as the surface treatment of body filler, primer filler, lacquers and paints. The FiboTec multi-hole is based on a string of numbers known as the Fibonacci Sequence. As a hole pattern, the resultant spiral structure, which crops up time and time again in nature, provides superior dust extraction, significantly reduced clogging and therefore longer abrasive life.
