The very particular blending of the components of this sanding wheel, silicon carbide plastic foam, has been specifically studied by our chemical lab to guarantee a unique compactness able to achieve an aesthetically perfect surface finish. It is specifically designed for working on the metal parts of spectacles, on soft metals (nickel silver types) and also boasts a high quality finish and ‘super finish’ on semi-finished products of harder metals.
Maximum recommended speed: 15-20 metres/sec.
