Rock Tumbler Belt Replacement 5-Pack for K1, K1 Pro, K3 – Includes 2 PU Belts + 3 Rubber Belts – Highly Recommended for Durability & Breakage Resistance – Not for K2 or K4 Model

These belts are perfect size replacements on my tumbler! I never wanted to be particularly done with a tumbling session and have to wait for a replacement,these are perfect.By the way the original belt is going to last a long while,very good quality.

USED ON A gY-ROC B TUMBLER AND IS WORKING VERY WELL.

The media could not be loaded. I have a no-name rock tumbler with no company website. Not a junker, but not high dollar either. Its belts, when broken, are 8 7/8” long. So if your current belts are between 8 3/4” and 9” (possibly even 8 1/2”) these will work fine. No slip, good grip, and the one I’ve put on it has lasted 9 days so far (a record).

Rubber belts for your tumbler break - no matter what you do. These replacement belts have worked very well for me. Some have lasted for close to a month with my Komestone tumbler before breaking. You can't tumble without belts - I always make sure that I have some on hand. I'd definitely recommend these and will be sure to purchase more in the future.

They were easy to put onto my rock tumbler. They look to be thicker and more durable than the original O ring attached. The test is how long these will last. I'm hoping longer than the original o ring on my rock tumbler!

My rock tumbler belts wear out every 20-30 hours and these are handy to keep on hand to replace them.

The belts appear heavy duty.However, they only last on my rock tumbler for about two weeks, than I'm replacing them again.

First band broke after just 5 days of use on a rock tumbler!
