Everything You Need For Tumbling!

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

  • a heavy-duty tumbling machine
  • a durable, three-pound-capacity tumbler barrel
  • a booklet: "Guide for Rock Polishers"
  • enough grit and polish to process a batch of stones
  • enough rough rock to run the tumbler
  • a jewelry kit to make gifts from your tumbled stones
  • Thumler's Tumbler Warranty

  • Perfect for the beginner! A small, single-barrel tumbler is a great choice for your first tumbler or a tumbler that you are giving as a gift. They are the least expensive to purchase and have the lowest operating cost (the cost of grit, polish and rough rocks). This rock tumbler kit has everything you need to start tumbling right away.

    You can buy this rock tumbler kit with confidence:

    This is one of the tumblers that we 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.

    Optional Rock Tumbler Accessories:

    A) Refill kits with all rough rock and grit needed to run the tumbler are available.

    B) Most rock tumbler instructions tell you to tumble your rough rocks with coarse grit for seven days and then move on to fine grit. This will work. However, we often run the rocks a second week in coarse grit to make them more rounded in shape. We feel that the second week makes a big quality difference in our stones.

    C) 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.
