Depressed centre metal cutting discs are manufactured using aluminium oxide abrasive grit with fibreglass reinforcing and resin bonded to provide both safety and optimum cutting performance. Discs with a 1.8mm thickness permit fine cutting where necessary on stainless steel and high grade metals. They have been developed to make angle grinders more versatile in use by allowing better access in some applications. Metal cutting discs must always be presented to the workpiece at an angle of 90ordm. For use with a variety of machines, mini grinders to stationary cutting off machines.
