Berry's Model QD-500 Vibratory Tumbler is an industry first. With a patented quick-detach system, you can remove the bowl from the base completely, keeping spills and messes to a minimum as you pour your brass and media into a separator without having to handle the entire unit. The large, smooth bowl aids in turning and moving the brass and media for quick thorough cleaning. The clear domed polycarbonate lid lets you see the progress without turning off the motor. All other parts are made in the USA.
