Tumblers Buying Guide

When selecting which rock tumbler is ideal for you, there are a few things to look for and consider:

Barrel Size:

When picking a tumbler, one of the most important considerations you’ll have to make is the barrel size.

When buying a tumbler, you’ll find that the sizes are measured in pounds, with 3 lb being the most popular size for beginners and enthusiasts.

The size you pick is mostly determined by two factors: the number of rocks you want to tumble on at one time and the size of the rocks you want to tumble.

If your barrel is too big, you may have to make up the difference with grit and other media.

Always attempt to fill your barrel with your rocks to around 65-75 percent capacity. If you buy too big, you’ll have to buy additional pebbles to fulfill the tumbler’s minimal requirements.

Barrel Material:

Barrels were originally constructed of items such as paint cans and were noisy enough to wake your neighbors in the middle of the night!

For the best rolling of the pebbles and noise reduction, barrels are now generally composed of plastic or high-quality rubber.

The amount of noise the tumbler creates is one of the main worries individuals have while considering whether or not to go into rock tumbling. After all, these machines are on for weeks at a time, running 24 hours a day. Rubber barrels also aid in the rolling of your rocks and provide a more cushioned surface to protect them from harm.

Multiple Barrel Configuration:

Simply sort your rocks into different barrels according to their hardness.

Another significant advantage of a multi-barrel tumbler is the ability to run batches in phases — let me explain. You won’t be able to tumble other batches until the current batch has completed its cycle, which might take many weeks.


If you’re buying something other than a toy tumbler for a child, you’ll want to go with one of the more reputable brands, which have the superior build quality and longer warranties.

Remember that your tumbler will be running 24 hours a day, seven days a week for weeks at a time, thus the motor and belt (among other components) must be of excellent quality if you want it to last.

Greater brands will have better warranties as well. A one-year parts and labor guarantee will be included with most Lortone and Thumler tumblers.

Rotary vs Vibratory Tumblers

The most popular form of rock tumbler is a rotary tumbler, which is what most people think of when they think of a rock tumbler. However, there is another type of tumbler that may be used for a variety of purposes and is worth addressing in this article.

They’re known as vibratory tumblers, and they’re best employed for the tumbling process’ latter, polishing phases. Without getting into too much depth (I have covered this in my rock tumbling tutorial), a vibratory tumbler should only be used to polish rocks, not to shape them.
