Can you put regular rocks in a rock tumbler? You will want to avoid soft rocks as they might just fall apart when you add them to a rock tumbler and some really hard rocks might damage your tumbler. 2. How long does it take to polish rocks in a rock tumbler? For beginners, the answer can come as a bit of a shock as it could be one week or one month to tumble rocks to a polish that you are happy with. Patience is a virtue in this hobby. The end result can be worth the wait as they look great when they are finished. 3. How to apply lubricant to the belt? Apply the lubricant to the gear surface of the belt, then gently rotate the belt drive pulley to ensure the lubricant is evenly distributed over the belt's teeth. Any type of lubricant can be used to lubricant the belt. 4. Does the product come with an instruction manual? Yes. A detailed instruction manual is included to guide you step by step, from loading stones to adding grit and polishing. Each stage is explained in the manual for beginners. 5.What other items can you tumble? If you’ve found some coins then you can throw those in the rock tumbler. A rock tumbler will help clean it giving it a nice shine. Other than coins you can also place shells inside a rock tumbler. IMPORTANT TIPS 1. Mind the Noise: Tumbling machines can be quite noisy. We recommended that you keep it in the garage so that you don't disturb your neighbors. 2. Don't wash grits down the drain! It will create a clog that is impervious to drain cleaner. Rinse the grits steps outside using a garden hose. 3. Use mineral oil for extra shine! If you want your finished stones to be really shiny, coat and polish the stones with mineral oil.

Review: Great customer service for a good product! - Great customer service. I had a problem and they sent me a whole outer unit. Works very well now. Easy to use and grandkids live putting their small river bed finds in. I like to tumble my jade for Indian jewelry. It is a little noisy but much quieter than my old tumbler. Feels very heavy duty. I have it in same room as my baby chicks who seem to accept it as background noise. Would buy again as gift.
Review: Great customer care update - I give this a 5 star mainly due to Daisy in customer support. When the tumbler arrived it would not work at all. I was going to return it, but i noticed the great customer service reviews. Not only did I get a rapid response , but was given concise instructions on what to do. I took a video, sent it to Daisy and the very next day was told that the problem was determined it to be a faulty adapter. She sent a new one, which arrived quickly. I plugged it in and it has been running for the past five days without a hitch. Thank you Daisy. Time will tell if I can polish rocks or not. After using the tumbler for about two weeks, polishing rocks that had already been worked using another tumbler, I am thoroughly happy. Considering the cost I feel it is a great little machine. I must admit that I purchased some 8000 grit, and found it did a better job than the 1200. The tumbler is quiet, (I have it in my den), runs without a hitch, and is easy to use. The combination of great customer support, and a machine that does all I want, I would recommend this, especially to the beginners and young geologists. The rocks look better than my mediocre photos.

### ⭐⭐⭐⭐⭐ Pretty Kool Rock Tumbler!
*by M***N on March 16, 2026*

This is my first experience with rock tumbling, and this tumbler seems ideal for beginners. It seems solid and well constructed. I like being able to set the speed (3 speeds), and number of days to tumble. It’s not super quiet, but not too noisy. I have mine in the garage, and can’t hear it at all from the house. They sent a bonus bag of nice assorted rocks to get started, and enough of the various grits of tumbling media to get started.
