Notes

About Rotary Tumbling: Rotary tumbling is a proven mass finishing technique for burnishing or cutting surfaces. Results develop over several hours or days, making it the slowest of all mass finishing methods, but it offers the greatest capacity for cost. Use steel media with detergent to burnish and work-harden pieces, or plastic media with detergent for aggressive cut-down.

Best for: Shining and burnishing metal surfaces.

Limitations: Slowest mass finishing technique. Not recommended for final polish on broad, flat surfaces.
