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 a couple running at our office while you are reading this. If you need information about rock tumbling we have authored the internet's largest library of rock tumbling articles. If you need help with a tumbler purchased from us you can find our contact information at the bottom of your invoice and get in touch with us. Very few retailers are able (or want to) offer this service.

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 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 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 1/2 of the grit used by a rotary tumbler. You will save lots of time and electricity too! Produces an amazing polish on agates, jaspers and many other materials. Very quick and easy to clean. You can remove the lid to inspect your rock in the middle of a run. You must be dedicated to use this machine because it must be glued to a concrete block - but you will be smiling when you see your bright polish.
