Thumler's Two-Barrel Rock Tumbler



Here's what you get in this A-R2 rock tumbler kit...



  • A heavy-duty tumbling machine
  • 2 durable, three-pound-capacity tumbler barrels
  • A booklet: "A Guide for Rock Polishers"

  • To run this tumbler you will need four pounds of rough rock. and two four-step grit kits (one for each barrel). If this is your first time tumbling we highly recommend our Mixed Jasper. If you would like to purchase everything needed in a single kit, we offer that below! We also offer refill kits with all rough rock and grit needed to run a 3-pound barrel. For this tumbler you would need to purchase TWO 3-pound refill kits.

    Perfect for the beginner! A small, two-barrel tumbler is a great choice for your first tumbler or a tumbler that you are giving as a gift. Two barrels give you a lot of advantages: 1) you can tumble more material, 2) you can tumble rough at two different stages, or, 3) if two people share the tumbler each one can have a barrel.


    You can buy this rock tumbler with confidence:



    This is a tumbler that we highly recommend for beginners. You can find less expensive machines on the market but most of them are made from plastic and have a plastic barrel which will not last through more than a few loads of rock - and the rocks rolling in that plastic barrel will make a lot of noise!

    This machine has durable rollers and bearings that are made to last over years of frequent use. The motor is properly sized and overload-protected. If it overheats it will protect itself by shutting off automatically. The soft rubber barrel is thick enough to last a long time. If you use this tumbler a lot and a barrel, bearing, or belt wears out you can purchse inexpensive replacement parts and fix it easily yourself.

    Rock Tumbler Plus Grit and Rock



    Here's what you get in this A-R1 rock tumbler kit...



  • A heavy-duty tumbling machine
  • 2 durable, three-pound-capacity tumbler barrels
  • A booklet: "A Guide for Rock Polishers"
  • Four pounds of rough rock selected for the beginner.
  • Enough grit and polish to process the rough

  • Here is the sure and easy way to get started with rock tumbling. Purchase the Thumler's A-R2 and supplies kit. This kit includes all of the supplies that you will need to run the tumbler. It includes four pounds of mixed jasper rough rock that has been specially selected for tumbling success. These are rocks that polish well and are sized just right for a three-pound barrel. The kit also includes all of the grit and polish that you will need in pre-measured packets. Just open the packet and dump into the barrel. Most of the people who buy an A-R2 tumbler from us purchase this kit.

    Optional Rock Tumbler Accessories:

    Many experienced people have a special barrel that they only use for the polishing step. This significantly reduces the chance that grit - embedded within the rubber barrel - will cause scratches on your stones during the polishing step. We always have an extra barrel for each of our tumblers and use that barrel exclusively for the polishing step.

    A Rock Tumbler Story:

    My father bought a Thumler's Tumbler about 35 years ago and gave it to me as a Christmas gift. I still have it, it still works great, and it has run through hundreds of grinding and polishing steps. We oiled it regularly, replaced a few belts (a very easy job) and replaced the barrels twice. The service that we received from that tumbler convinced me that it was a durable machine that was made to last a long time.

    In 2006 I was shopping to purchase a new tumbler for family use. I was amazed to see machines that are almost identical to the one that my father gave to me a long time ago were still being made. Very few products persist so long in the marketplace without major changes. I purchased another Thumler's Tumbler with two three-pound barrels and have been pleased with the same great performance.
