A coated abrasive can be a abrasive cloth or film which has sand grains attached to it. Flexibility is achieved through the backing material while cutting power is delivered by the abrasives. Coated abrasives range from rough to fine polish grit and can be used throughout different processes. For example, coated sandpaper saw used in woodworking to smooth rough cut boards, while coated belts are mounted on machines for large scale metal surface polishing. Coating the covered backs of the sand helps disperse the grains of abrasives for more significant results.
