Abrasives and Sand Paper

An abrasive is a material, often a mineral and usually in the form of sand paper, sanding discs, sanding belts, sponges, or pads, that is used to shape or finish a work piece through rubbing which leads to part of the work piece being worn away. While finishing a material often means polishing it to gain smooth reflective surface which can also involve roughening as it satin, matte or beaded finishes.

Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic and technological applications, This gives rise to a large variation in the physical and chemical composition of abrasives as well as the shape of abrasive. Common uses of abrasives include grinding, polishing, buffing, cutting, drilling, sharpening, lapping and sanding. For simplicity, "mineral" is used to refer to both minerals and mineral-like substances whether man-made or not.

Files are not abrasives. They remove material not by scratching or rubbing but by the cutting action of sharp teeth which have been cut into the surface of the file, very much like those of a saw. However, diamond files are a form of the coated abrasive (as they are metal rods coated with diamond powder).
