Additionally, they fracture during use to maintain sharp abrasive edges resulting in a 30% faster cut and lasting 2x longer life than conventional ceramic abrasives. 3M Cubitron II File Belt 786F is available in various coarse grades and various widths as well as various lengths; it can be fitted on to various types of file belt machines available on the market.
