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 thermally 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. We also have a page that answers many of the common questions customers have had when operating Thumler's A-R2 tumbler available here.

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 in the 1960s 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. I kept it clean, oiled it regularly, replaced a few belts, replaced the barrels twice, replaced the motor twice, replaced the drive and idler shaft once. The service that I received from that tumbler convinced me that it was a durable machine that was made to last a long time. That tumbler is still in service. We use it to test some of the roughs that are sold on this website.
The Thumler's rotary tumblers sold on this website are almost identical to the tumblers that were sold 50 years ago. In fact, most of the replacement parts sold today still fit those original tumblers! Very few products persist so long in the marketplace without major changes. Many of our customers are using tumblers with their grandchildren that they received as a gift during their own childhood.
