The Frankford Arsenal Platinum Series Rotary Case Tumbler is a high-capacity brass cleaning system designed for reloaders who process significant volumes of ammunition. Unlike vibratory or ultrasonic tumblers, this rotary case tumbler uses stainless steel media in a liquid bath to deliver faster, more thorough cleaning. The system's large 7-liter drum handles up to 1,000 rounds of .223 brass per batch, making it ideal for serious handloaders and competition shooters who need pristine prep work without the endless manual labor.

Rotary tumbling with small stainless steel pins penetrates deep into case interiors and primer pockets—areas that conventional vibratory tumblers often miss. The drum features a molded rubber lining that protects brass from dings while dampening noise during operation. Clear end caps let you monitor progress without stopping the machine, and a set of sifting end caps speeds up media separation when the cycle finishes. The built-in timer runs from 0 to 3 hours and shuts off automatically, so you can set it and focus on other prep work.

The Platinum Series comes ready to work: 5 pounds of 304 stainless steel media pins (worth nearly $50 on their own) and a sample packet of Frankford Brass Cleaning Solution are included. The maintenance-free geared drivetrain eliminates belt replacement headaches. You can also run the tumbler with just Frankford Brass Cleaning Solution and water if you prefer, though the media pins deliver the cleanest results for primer pockets and case interiors.
