A rotary tumbler will reshape angular and irregularly shaped rocks into well rounded, near-spheroidal specimens if left in the tumbler long enough. In contrast, vibratory tumblers will tend to retain the overall shape of the original rock, just smoothing the contours to a fine polish.

We’ve taken the classic performance of existing rotary tumbler and improved the design and technology to bring them into the 21st century. Not only is the Tumble-Bee a technologically advanced rock tumbler for adults and kids, but it’s also a modernized, safe rock polisher tumbler.
