AS-9
Product Description: Similar to the AM-8, the AS-9 is engineered for hand stoning EDM scale surfaces. It can be used with polishing machines, but the special formulation provides a fast, smooth cutting action during hand stoning. Use either with a lubricant or dry.
AO
Product Description: AO is a perfect all-around aluminum oxide stone. It has excellent breakdown characteristics and yet retains shape well, especially when polishing mold cavity details. Because the AO is filled with lubricant during the manufacturing process, it does not require lengthy pre-lubrication. 220 grit is an ideal "start up stone" for machined surfaces. The use of lubricant for all grit sizes is recommended. Grits 220 and 320 work well in removing EDM scale.
