Fine-Polishing Media for Steel, Stainless Steel, and Hard Metals
This nonabrasive media leaves a very shiny surface. Choose the shape that best matches the contours of your part and a size that’s large enough not to lodge in recesses and holes. Use with liquid compounds in tumbling and vibrating machines.
