Rock Tumbler Comparisons and Reviews

We have sold thousands of rock tumblers. From that experience, we sell only those tumblers that have been successful with our customers. We don't sell cheap plastic-barrel tumblers that make a lot of noise or imported tumblers that quit working after a few batches of rock. The tumblers we sell will last through years of proper use. We also sell all of the supplies that you will need to enjoy the rock tumbling hobby. We have been in this business for years, and our ability to serve our customers is what makes us successful.

The members of our staff have been using rock tumblers for decades. We probably have tumblers running at our office while you are reading this. If you need information about rock tumbling, we have authored an extensive library of rock tumbling articles - with every article written from experience. If you need help with a tumbler purchased from us, you can find our contact information at the bottom of your packing slip and get in touch with us. Today, a lot of tumblers are sold by merchants who don't know anything about rock tumbling, or those who sell anonymously and are impossible to contact when you have a simple question. You can read our customer reviews here, and some of them were probably written yesterday or this morning.

Thumler's A-R2: The Thumler's A-R2 tumbler has two three-pound barrels. It is very easy to use, and the soft rubber barrels will tumble your rock quietly. Having two barrels makes it easy for two people to share the same tumbler. Or, one person can experiment with different types of rock, or run rocks at different stages of the tumbling process. (We own two A-R2 tumblers and run one of them frequently.)

Vibratory Rock Tumbler Comparison


The table below compares features of every vibratory rock tumbler that we sell. Vibratory tumblers process rock in less than half the time required by a rotary tumbler. They also save you money by using a lot less grit and polish (less than 1/2 as much as a rotary tumbler of the same capacity).

Age Recommendation for Vibratory Tumblers: These are tumblers that require a bit of attention and are recommended for adults. Find out why.

We share information and videos on how we use the Lot-O-Tumbler in an article: How We Use the Lot-O-Tumbler, and how we use the Thumler's UV-10 in an article: Operating the Thumler's UV-10 Rock Tumbler.

Picture Tumbler Model / Description Barrels & Rock Capacity Price:
Single Lot-O tumbler
Lot-O-Tumbler Single: Polishes four pounds of rock in about a week and uses less than half of the grit required by a rotary tumbler. You will save lots of time and electricity too! Produces an amazing polish on agate, jasper, and many other materials. Quick and easy to clean. Just remove the lid to inspect your rock in the middle of a run. Requires dedication because this machine must be glued to a painted concrete block - but you will be smiling when you see your bright polish.   :-)
Barrels: One

Capacity: About Four Pounds
Currently Unavailable

Lot-O-Tumbler
Lot-O-Tumbler Twin: Same as the Lot-O-Tumbler Single above - but with two barrels. The Lot-O-Tumbler Twin will process about eight pounds of rough rock. A very small price increase for the ability to polish twice as much rock.
Barrels: Two

Capacity: About Eight Pounds (four in each barrel)
