Diamond grinding wheels can also be metal bonded. The various bonding agents give the wheels different grinding properties, as well as different properties with regard to safety. Abrasive and polishing belts and discs are composed of a flexible base of paper or fabric to which the abrasive is bonded by means of a natural or synthetic adhesive.
