Aluminum Oxide is the most commonly used abrasive. Best-suited for general purpose deburring and blending, it is tough, economical, and fracture-resistant. Commonly used on ferrous alloys, high-tensile materials, and wood.

Diamond is one of the hardest and durable abrasive materials. Due to being constructed of diamonds, the cutting depth stays the same throughout its life for better control, reach and precision. Commonly used in grinding and polishing ceramic, stone and aluminum alloy.
