How to select a tumbler:

Rotary tumblers round out and grind stones faster than vibratory tumblers. However, vibratory tumblers often provide a better prepolish and polish.

Ideally, one would have a rotary tumbler for the grinding stages and a vibratory tumbler for the prepolish and polish stages. Owning two tumblers isn't practical for non-professionals. So, if you want quick results, get a rotary tumbler.

If you are tumbling rounded, river worn alluvial material, or beach stones, the fast grinding speed of rotary tumblers isn't an advantage and we would then advise getting a vibratory tumbler.

Standard tumblers are set up for stones no larger than 1-1/2" in diameter. If you are going to be tumbling larger material, you should consider the Covington 40 Pound Production Tumbler.
