Your cart is empty.These belts are compatible, and will fit all variations of the Thumler tumbler brand units that utilize the 1/4" wide drive belts. If your Thumler tumbler has a thinner belt, 1/8", these will not work, you will need to purchase the "thin" series belts.

I had forgotten how fast the drum spins when the drive belt was new. Mine must have been slipping quite a bit. Now it takes half the time to get the same result. The fit is perfect, Time will tell how long they last, but so far I'm very impressed. Well worth the price.

I bought these for my Thumlers Tumbler Model B. The belts have so far lasted from a day to 5 days before they break. My Tumbler is in excellent condition and the belt I replaced was on there for over a year prior to breaking. I no not overload the tumbler is is running well under weight. Very disappointed with the quality of these belts.

We looked everywhere for these, and almost gave up our dreams of tumbling rocks. We’ve only used one, and it’s worked perfectly so far. I definitely see us getting our money’s worth. I just hope they are still available years down the road when we end up needing more.

If you have a Thumler Model 15 or two or three you know you will need to keep these on hand. I have bought them from Thumler and various other sellers. These are the best I’ve bought so far. Mine were black and feel very sturdy, all the others I have purchased have been clear. Admittedly I am hard on them, running heavy stuff so these are getting the job done with no complaints.
