The 3M Cubitron II 987C fibre disc offers a higher removal rate and service life than other fibre and sanding discs. Our sanding discs are equipped with 3M precision molded abrasive grain combined with a stiff fiber backing for higher productivity in medium and heavy removal applications. Use the 3M Cubitron II fibre disc 987C to achieve exceptionally high removal rates with lower contact pressure and to allow maximum ease of use for demanding tasks. Our high-performance discs are ideal for removing welds and chamfering, grinding and fading. An integrated grinding aid makes the grinding wheel an excellent product for all types of metal. It provides a cooler cut on stainless steel and heat-sensitive metals such as nickel alloys and titanium, reduces tarnish and oxidation of the metal and also reduces the likelihood of heat-induced stress cracks. Therefore, our sanding discs are superior to competitive products in service life and performance. The sanding discs contain 3M precision molded abrasive grain that forms triangular tips that cut the metal and do not furrow or "plow through" like conventional abrasives. These tips break off and thus sharpen themselves continuously so that extremely fast cutting is possible. Our discs have a tough, stiff volcanic fibre backing that is wear-resistant and handles demanding sanding applications. They are ideal for removing rolling skin, pitting and defects.
