Get professional rock polishing results with this Lortone double-barrel rock tumbler and deluxe rock tumbling kit!

Using the tumbling media (i.e. tumbling grit), instructions, and high-quality rock polisher inside this polish kit, the agate, chalcedony, jasper, rose quartz, and other rock samples in your rock mix will have a sleek and smooth finish. This quiet, durable tumbler can hold up to 6 pounds of rock (3 pounds in each barrel) for quantity tumbling and is an excellent choice for any rock tumbling hobbyist or pro.

The Lortone 33b Rock Tumbler Kit has everything you need to get started:

  • the double-barrel Lortone 33B rotary rock tumbler
  • 2 pounds of select tumbling rock mix
  • enough 4-stage fine grit to tumble and polish 12 pounds of rock
  • rock tumbling instructions

This Lortone model rock tumbler features patented rubber barrels with a quick-seal cover and a powerful continuous-duty electric motor. The tight-sealing rubber barrel not only produces excellent results and beautifully polished pieces, but it also provides extra sound absorption for quieter operation. This double-barrel tumbler is capable of running 24 hours per day for years and can tumble twice as much rock as a single-barrel tumbler.

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

Get an extra drive belt with your tumbler to ensure that you never miss a day of rock tumbling fun!
