This is a two-barrel rotary rock tumbler with rubber drums, each holding up to 3 lb of rock, grit and water. The low-speed motor is built to run for days, which is what polishing stones actually takes. Two drums let you run a coarse stage in one barrel and a finer stage in the other, or tumble two batches at once, which single-drum budget tumblers cannot do. Rubber barrels keep the noise down compared with plastic or metal drums, though rotary tumblers still hum for weeks on end. It suits hobbyists polishing batches of agate, jasper, glass or small metal parts who accept slow turnaround in exchange for a simple, quiet machine.

Owners of this class of dual-drum rotary tumbler generally report good polishing results on agate, jasper and glass, and value running two barrels at once. Complaints center on slow turnaround, lid leaks when barrels are overfilled, and the need to buy grit separately.
This dual drum rotary rock tumbler gives rocks, semi-precious stones, glass and even metals a smooth, polished finish.
Each drum holds 3 lb. The barrels are rubber for quieter operation. The tumbler runs at a low speed and is designed to run for days at a time for a smooth, lustrous finish.
