Mirror-Finish Polishing Media for Steel, Stainless Steel, and Hard Metals
Often used as the final step after other media, this type of media is also good for use on fragile parts and won't contaminate nonferrous materials. Choose a size that’s large enough not to lodge in recesses and holes. Use with liquid compounds in tumbling and vibrating machines.
