Tumble polishing, or tumbling, is a technique for smoothing and polishing a hard substance. Our rock tumblers allow you to create fascinating specimens for gifts, collections and more with everything that is needed to turn ordinary rocks into polished gemstones. A unique and interesting hobby, rock tumbling allows you to discover beauty lurking beneath the surface.

You can choose between two styles based on your needs: single barrel or double barrel. The single barrel kit includes a 3 lb. capacity rubber barrel tumbler, rocks, grit package, jewelry making kit and detailed guide manual. For larger loads, the double barrel tumbler has a 6 lb. capacity and grit pack only.

The Accessory Kit rounds out (pun intended!) any tumbling enthusiast’s supplies. Included is a grit pack, 4 lbs. of rock, a jewelry making kit and a 115V continuous overload protector motor.

Our polishing products come with a guarantee on both the barrel and the liner. They are appropriate for use by hobbyists ranging from novice to expert, laboratories, schools and industry for an unlimited variety of tumbling and mixing operations.
