It's tumbling or deburring media. It's used in a vibrating or rotating device to clean, deburr and/or polish bulk parts or pieces. There are literally thousands of different shapes and materials used depending on what's being cleaned or deburred and the type finish desired. Tumbling units can be as small as a few pounds capacity up to units that can process over a ton of parts.
