The Tumble-Bee 2x2 lb barrel rotary rock tumbler comes complete with two 2 lb capacity rubber barrels. This model is a great choice for small scale tumbling and polishing of stones, glass and metals. Two barrels allow you to tumble two different materials or use two different abrasives at once. It's also a great choice for two people to use at the same time. With industry leading designs and features, the Tumble-Bee is a durable, modernized rock tumbler that is very user-friendly and easy to use. Made of ABS plastic with a metal reinforced bottom, the Tumble-Bee housing is rust-free and free of sharp edges. Built-in barrel guides keep your barrels running true while you tumble. Its lighted on/off power switch easily indicates if your rock tumbler is on or off. The powerful 115V continuous AC fan-cooled motor comes installed with a thermal overload protector. Designed to tumble 24/7 and comes backed with a one-year warranty.
