Fibre Disc 3M 785 C diameter 127 grain 60, 3M has a wide range of fiber discs for various applications and materials (metals). Depending on your needs, you can choose the right product according to the provision, the cutting power. The fiber discs 3M T 785C, 985C and 988C are provided with the ceramic mineral 3M Cubitron. This 3M patented ceramic mineral is developed to ensure a more incisive cut and a longer life. Thus the discs Cubitron fibers combine longer service with superior results and improved productivity. Features: 3M Fibre Disc 785 C Grain size 60, large grain, use: roughing Dimensions: 127 x 22 mm Drive high quality fiber for leveling extreme heat sensitive metals such as stainless steel and aluminum Mineral ceramic 100% Cubitron T II Grinding-Aid, high leveling anti-heating layer constant minerals break the as and generate less heat than other standard mineral advice: 3M Cubitron grains are chemically mineral products which are developed and produced individually with specific physical characteristics. Especially developed for use in grinding operations during which the same high quality and consistent benefits shall be provided. This unique aggressiveness, microscopic crystalline structure constantly exposes new grains. Thus, the product maintains a constant aggressiveness. You can now trust a sustainable economic and abrasive solution that offers concrete production advantages compared to traditional abrasives.
