The Lyman Turbo 1200 Series Tumblers feature a beefed-up suspension system and built-in “exciters” for better tumbling action and faster cleaning. The drive system has improved air flow for cooling and longer motor life. The PRO Case tumbler bowl system offers a built-in sifter lid for easy sifting of cases and media at the end of the polishing cycle without requiring the additional purchase of a media sifter.
