The fine, smooth and reflective surface of a finished product or its rough, matte and beaded finish is achieved through the use of abrasives. Abrasives are widely used in industries, machine shops and even at home to shape or form materials. They are made and manufactured according to the purpose like the coated (used in rotary sanders, handpads, etc.), bonded (used as a modelling scale) among others. The quality of the finished product depends on the kind of abrasives being used coupled with the necessary skill.
