The Frankford Arsenal® Platinum Series Rotary Tumbler delivers a whole new level of brass cleaning performance. When rotary tumbled with our stainless steel pins in a liquid bath, brass will get much cleaner and work much faster than ultrasonic or vibratory tumbling methods. The small stainless pins remove carbon from inside cases and primer pockets to deliver like new brass. The large volume drum holds up to 1000 pieces of.223 brass and has a molded-in rubber lining to protect brass and dampen noise during operation. A built-in timer in the base can be set to run from 0 to 3 hours shutting off automatically. A set of sifting end caps is also included to assist in separating the stainless media once tumbling is complete. The tumbler can effectively clean without the use of stainless media pins with a mixture of Frankford Brass Cleaning Solution and water (use of media pins ensures primer pockets and inside of cases are perfectly clean). Five pounds of 304 stainless media pins and a sample packet of Frankford Brass Cleaning Solution are included. It’s the most effective brass cleaning process available with a large 7 liter capacity.
