Thumler's MP-1 Rock Tumbler Kit: Learn about rock tumbling with a quality machine at a low price. Includes all supplies needed to produce your first batch of tumbled stones. Convenient refill kits are available here. Has a soft rubber barrel for quiet operation. Perfect for the beginner.



Thumler's A-R1: Larger and more durable than the MP-1 shown above. The barrel will quietly tumble about twice as much rock. Has a thermally protected motor on a metal frame. Will last for years. You can get just the tumbler, or a kit that includes rocks, grit, a small jewelry kit and instructions. Refill kits are available here.




Thumler's A-R2 is our best-selling tumbler. Why? TWO 3-pound barrels enable you to: A) tumble twice as much rock; B) tumble two different materials simultaneously; C) tumble materials in two different steps of the tumbling process; or, D) allow two people to share the tumbler -- with each person getting their own barrel. Those are the extra benefits you get for just $40 over the price of an A-R1 tumbler!




Thumler's A-R12: A large tumbler with a 12-pound capacity barrel. Used to quietly tumble a lot of rocks or to clean brass ammunition casings. With minor adjustments it can easily be converted to run two 3-pound barrels (video here).
.


Thumler's Model B: The largest rotary tumbler that we sell. Has a 15-pound capacity barrel and a larger motor than the tumblers above. Used for tumbling rocks, but it is very popular for cleaning brass casings. Has a thick rubber liner to prevent leaks and to run quietly.

Lot-O-Tumblers are being manufactured again, and we have a few Lot-O-Tumbler Twins (the two-barrel tumblers) available for purchase. We hope to have Singles available soon.
