Grinding and Sharpening
Aluminum Oxide Grinding Stones (red/brown) are ideal for sharpening, deburring, and general purpose grinding on most materials. Silicon Carbide Grinding Stones (blue/green) will work in the same way, but will withstand harder materials like stone, glass, ceramic, and porcelain. Aluminum Oxide Abrasive Wheels work best for cleaning rust removal, as well as light polishing.
