The Sevorley 11 lb Rotary Tumbler is a barrel tumbler for polishing, grinding and buffing jewelry, gemstones and coins. It uses a gear transmission instead of a belt, which the maker says runs smoother and more stable, and it offers five speeds, bidirectional rotation and a 0-60 minute timer. The sealed polycarbonate barrel has a locking buckle and airtight seal, and a rubber base keeps it steady. It suits hobbyists and small shops with a batch of stones or metal parts to finish; belt-driven drums of the same size are the usual alternative, and the gear drive and timer are its main edges over them.

Owners of this class of gear-driven rotary tumbler report steady running and useful speed and timer control, but some find the loaded barrel heavy and the motor louder than hoped.
This rotary tumbler polishes, grinds and buffs jewelry, gemstones and coins. It has an 11 lb capacity. An upgraded gear transmission runs smoother and more stable than belt-driven designs.
Used with iron beads or steel balls, the barrel works on the principle of centrifugal motion. This improves polishing efficiency five to ten times and refines surface precision.
The polycarbonate barrel is sealed to prevent leaks, with a tight-locking buckle and an airtight seal. A wear-resistant rubber non-slip base keeps the tumbler steady. It has five speeds, bidirectional rotation and a 0-60 minute timer.
