The Cyclone Rotary Tumbler takes brass cleaning to a whole new level. The rotary tumbling action combined with the stainless steel media and liquid cleaning solution gets brass cleaner on the outside than vibratory tumbling methods. The small stainless pins easily slip inside cases and into primer pockets to provide superior cleaning action in these areas. Something that vibratory tumbler will not do! The large capacity drum holds up to 1000 pieces of .223 brass and features a rubber lining to protect brass and greatly reduce noise during operation.
