Rotary Tumblers Vs. Vibrating Tumblers

Rotary Tumblers vs. Vibrating Tumblers


Rotary tumblers and vibrating polishers are two different types of polishers. They don’t do the same thing but each has its own usefulness and their pros and cons.



This chart shows the differences comparing quality rock tumblers such as Covington, Thumlers, and Lortone. Lesser quality tumblers like Smithsonian, Harbor Frieght, Rolling Stones, and other cheap tumblers aren’t included because their quality is so bad they don’t usually last more than a month.
