Aluminum Oxide has a blocky shape with multiple, sharp cutting edges that penetrate workpieces, dig-out micro-chips and leave exceptionally clean etched surfaces. It is effective on metals, glass, ceramic, marble, granite, and other stone. It has a MOHS hardness of 9 which makes it a very tough and durable material. It is an excellent material for cleaning and providing a uniform surface or anchor pattern.
