The Tumble-Bee 1×4 is a rotary rock tumbler that comes complete with one 4lb capacity barrel. This model is a great choice for tumbling larger quantities at once and is the perfect size for professional tumbling of larger material such as stones, glass and deburring and polishing metals.
Included with the Tumble-Bee 1x4
* One complete 4lb rubber barrel
* One bottle of clean, lightweight oil
* One 3/64" Allen wrench
* Detailed instruction manual
Tumble-Bee rock tumblers are ONLY available in 115 volt power supply. They come with the standard U.S. plug.
Non-slip timing belt The grooved design in the Tumble-Bee’s timing belt prevents it from slipping off the pulleys, keeping your rock tumbler tumbling smoothly. It’s also made of strong polyurethane with embedded polyester fibers to reinforce the belt’s shape and to prevent the belt from splitting. Tumble-Bee is the only rock tumbler available on the market with this advanced feature.
Thermal overload protector Installed in every Tumble-Bee rock tumbler, the thermal overload protector automatically shuts off the motor if it overheats, protecting you and your rock tumbler.
On/off power switch The lighted power switch easily indicates if the Tumble-Bee is on or off, preventing you plugging/unplugging before and after use. While this might seem like a no-brainer, many tumbler manufactures skimp on this simple feature.
Shielded moving parts The motor and pulleys are shielded with a motor cover for your safety.
Rust-proof housing The Tumble-Bee is made of a hard, composite plastic to prevent rusting and to eliminate sharp, metal edges.
When packaged, Tumble-Bee tumblers have their drive belts taut which may keep the barrel from spinning freely in not adjusted. You can loosen and adjust the belt tension by removing the motor cover (please unplug the tumbler first) and loosening the mounting screws of the motor allowing it to slide slightly. Re-tighten the screws and plug in the tumbler to check the rotation. Repeat as needed until the rotation is right. Replace the motor cover and get to tumbling.
