Item Description

Get an impressive amount of rock polishing production out of this surprisingly compact unit! The Thumler's Model AR-12 Rotary Rock Tumbler holds a full 12-pounds of stones, jewelry or metal casings. The extra-large water-tight drum is rubber lined for smooth, quiet operation. Hexagonal construction turns stones evenly, and the polyvinyl barrel can't rust.
