Whether a pro or a hobbyist, you can polish rocks twice as fast with this quality Lortone 33B double-barrel rotary tumbler!

The two 3-pound-capacity barrels on this rotary rock tumbler provide the flexibility to:

  • Polish larger batches (up to 6 pounds at a time!), OR
  • Coarse-grind in one barrel while polishing in the second barrel

This double-barrel tumbler features patented rubber barrels and a continuous-duty electric motor. The tight-sealing rubber barrels on this heavy-duty Lortone model produce beautifully polished pieces as well as extra sound absorption for quieter operation. Lortone has a reputation for making durable, easy-to-use tumblers that will last for many years, and this Lortone rock tumbler is no exception!

A rotary tumbler has the advantages of removing all the rough edges to produce nicely rounded corners and is also suitable for tumbling hard minerals. It typically takes 4-6 weeks to completely polish a batch of rocks that were previously rough rock.

This 33b tumbler and polisher is capable of running 24 hours per day for years. A Lortone step-by-step guide to tumbling gemstones and rock polishing, plus operating instructions, are included. One-year warranty from Lortone.

Tumbling rocks and tumbling grit are available separately.
