Here's what you get in this A-R2 rock tumbler...
To run this tumbler, you will need between one and two pounds of rough rock for each barrel and two single-use grit kits (one for each barrel). 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.
Why Is This Our Best Selling Rock Tumbler?
The Thumler's A-R2 is perfect for a beginner or a person with rock-tumbling experience. Two barrels give you a lot of options:
1) you can tumble more material,
2) you can tumble two different materials,
3) you can tumble rough at two different stages, or,
4) if two people share the tumbler, each person has their own barrel.

We have sold thousands of Thumler's A-R2 tumblers and know the questions that people commonly have. So, we prepared a page that answers the most common questions. You can also read this page and learn what you are getting into... Thumler's A-R2 Questions and Answers.
This is a tumbler that we highly recommend for beginners. You can find less expensive machines on the market, but many of them are made from plastic and have a motor that will not last through more than a few loads of rock.
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 purchase inexpensive replacement parts and fix it easily yourself.

We include 4 packets of coarse grit so you can run the coarse grit step twice, if desired. We also include 2 packets of ceramic media.

A Rock Tumbler Story:My father bought a small Thumler's Tumbler in the 1960s and gave it to me as a Christmas gift. I still have that tumbler. It still works great, and it has polished hundreds of batches of rocks. Now, almost sixty years later, that tumbler is still in service. We use it regularly to test the tumbling roughs that are sold on this website. We have kept it clean and oiled it regularly. In nearly sixty years it has needed a few new belts, a few new lids, a few retaining rings, two sets of barrels, and two new motors. The service that we have received from that tumbler is convincing. The Thumler's A-R2 tumbler is a very durable machine that is made to last a long time. We have sold thousands of Thumler's A-R2 rock tumblers to customers all over the United States and have received very few complaints. My father didn't realize that his gift of a tumbler would one day result in a family-owned and operated business that today employs his son, daughter, granddaughter, grandson, and daughter-in-law. Our business operates RockTumbler.com and publishes Geology.com - one of the most popular Earth science websites on the internet. The Thumler's A-R1 and A-R2 tumblers sold on this website are almost identical to the tumblers that were sold 60 years ago. In fact, all 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 A-R1 and A-R2 tumblers with their grandchildren that they received as a gift during their own childhood. If you have an old Thumler's Tumbler from your childhood, a good cleaning, a few drops of oil, and a new belt will likely make it run as good as new. Just follow our cleaning and oiling instructions. Your children might be delighted to be using the same tumbler that you enjoyed as a child. The Thumler's MP-1 tumbler, a "beginner's" grade tumbler, was first available for sale in 2009. We bought one of those early MP-1's in 2009, and we are still using it today. It has tumbled hundreds of barrels of rocks and is still going strong. We have changed the belt a few times, changed the barrel once, and replaced the motor once using these replacement parts. You will not get that kind of service out of a "toy tumbler". Happy Tumbling!
