A standard rock tumbler kit can be found at most toy stores. This rock kit usually contains the tumbler along with some rocks, grit, and a few jewelry findings. With proper care, a good rock kit can be used over and over and can last indefinitely. However, the small size and small power of the motor will limit the size of rocks that can be used. Should the tumblers break, it may be difficult to find replacement parts. More than likely you would be looking at buying a new rock kit.

The type of rock kit available from toy stores includes rotating or rotational rock tumblers. In a rotating tumbler, the rocks fall over and over, rolling around and polishing them as they collide with one another, similar to the way mountain rocks are polished by the steady collision with a mountain stream. It is advisable to choose a rock kit made by a company that has been around for a while in case you need a replacement part.

Vibration (or "agitating") tumblers are higher quality and generally more expensive form of rock tumbler. Instead of physically rotating the rock, vibration tumblers either use ultrasound or spin around the vertical axis. They work much more quickly, one to two weeks, as opposed to about a month for a rotational tumbler. They also maintain the essential shape of the rock, rather than producing a uniformly round rock. So unless you want all of your rocks alphabay tumbler to have the same basic round shape, you will need to consider a vibration rock kit. They are a bit quieter as well.

Size is extremely important. Rock tumblers are sized according to the weight of the load they can continuously bear. Since it can take a month or more for a rotary tumbler to polish a rock, it is important that the tumbler can handle the weight of the rock. The most common cause of rotor failure or broken belts is an overloaded barrel. Large barrels can hold both large and small rocks, but small barrels can only hold small rocks. This seems logical, but on the day that your tumbler breaks, you will regret purchasing a small barrel!
