Product Information

These include a heavy-duty tumbling machine with a built-in programmable timer, a leakproof tumbling barrel, 4 bags of polishing grit, and 1/2 pound of rough rocks. The idea is that over time, kids should be able to use the rock tumbler without a significant amount of adult supervision. Transform dull, coarse rocks into gorgeous, shining gemstones with these high-quality rock tumblers!

This hobby-quality rock tumbler gives a smooth, polished finish to rocks, semi-precious stones, glass, and even metals! We all want to take our rock collection to the next level, but we don’t want to spend a fortune doing it.For instance, as the machine functions on its own for weeks, leakage incidents could easily go unnoticed, which is why this feature is of great importance. The motor spins a pin on the bottom, which turns a hard rubber barrel through friction, while the end of the barrel is held in place by a pin. This style of tumbler features one barrel chamber where you place your rough rocks, water, and grit.

Some people choose 3 or 5 steps for their tumbling process, and some change the process depending on the stones. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. Because they involve fewer collisions, vibratory tumblers will change the shape of your raw stones less than rotary tumblers.For those seeking a professional-grade machine, the Tumble-Bee TB-22 includes a high-quality kit built to handle continuous use. Rock polishers have been used by jewelers and hobbyists alike in the past century because they provide excellent results when it comes to shining up rocks. This kit has everything you need including 1/2 pound of rough rocks, 4 bags of polishing grit, a strainer, and 5 jewelry settings.
