Abrasives are tools made with a material of certain hardness that is used for shaping or giving a fine finish to the material that is rubbed against it aka workpiece. The sharp, hard material used is called an abrasive.

Abrasive tools are made of many different abrasive grains and other materials. The grains used are very hard so that they can be used to give a shape, fine finish, or polish to the other materials. Abrasive tools can be used for working on gemstones, 유리, ceramic, stone, steel, and other metal or nonmetallic materials.

Centuries of breakthroughs witnessed advancements in abrasives. The Industrial Revolution fostered advancements in abrasive performance. The demand for higher abrasive performance led to the development of synthetic abrasives, often referred to as manufactured abrasives.

Coated abrasives are composed of abrasive grains that are built onto a cloth or paper backing then formed into a sanding belt, abrasive disc, abrasive roll, abrasive sheet, and flap-wheel, 등.
