Thumler’s heavy-duty Model “B” tumbler has a large-capacity drum that easily handles up to 15 lbs. of material for high-volume runs to help you clean a lot of brass fast. Used by serious reloaders, professional gunsmiths, and even industrial manufacturers for a variety of cleaning and polishing operations. The heavy-gauge steel hexagon drum has a rubber lining for ultra-quiet operation. Continuous duty electric motor delivers plenty of power without faltering, even on full-capacity loads, while the built-in circuit overload protection prevents overheating. The Model B is available alone. Never wears out, doesn’t need to be “renewed” like treated organic media, and won’t harm the brass. Stainless steel media (5 lbs.) also available separately.
NOTE: These must be run with a water/detergent/stainless steel pin mix to properly clean brass.
