  1. Can you put regular rocks in a rock tumbler? It is important to avoid soft rocks that may break apart in the tumbler or very hard rocks that could damage it.

  2. How long does it take to polish rocks in a rock tumbler? Beginners might be surprised to learn that it can take anywhere from one week to one month to achieve a polished finish. Patience is key, as the end result is well worth the wait.

  3. If your belt breaks, do not worry. Contact us for a replacement belt.

  4. What does it mean when my rock tumbler displays an "E"? An "E" indicates that the barrel is overloaded. Simply remove some rocks or water, or adjust the placement of the barrel, to resolve the issue.

  5. Can you tumble other items? In addition to rocks, you can also tumble coins and shells for a nice shine.

Remember these important tips: minimize noise by keeping the tumbler in a garage, avoid washing grits down the drain, and use mineral oil for extra shine. Plus, enjoy 24/7 support from KoolStone and a 2-year replacement warranty for any issues.
