The Platinum Series Rotary Tumbler delivers a new level of brass cleaning performance. Rotary tumbling with stainless steel media in a liquid bath gets brass much cleaner, and works much faster than ultrasonic or vibratory tumbling methods. The small stainless pins easily penetrate inside cases and into primer pockets to deliver unbeatable cleaning power. 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.
