Price History
- Tailored for KoolStone Tumblers: Every upgrade we make to our tumblers comes with matching improvements to accessories. Our new belts are designed to deliver smoother operation, stronger durability, and dependable performance over the long term.
- Engineered for C1 & C1 Pro: Exclusively developed for KoolStone C1 and C1 Pro models to ensure a precise fit. Using unofficial belts may look compatible but can cause extra wear and shorten your tumbler’s lifespan.
- High-Performance PU Belts: Built from advanced PU material that resists friction, heat, and wear. This upgrade means fewer belt changes and a more consistent tumbling experience.
- Optimized Material Selection: Through rigorous testing, our engineering team confirmed PU as the most reliable choice for rock tumblers—minimizing breakage and extending the belt’s service life.
- KoolStone Certified | Lifetime Coverage: Only official KoolStone belts come with full quality assurance. If your belt ever fails, we provide a free lifetime replacement—guaranteed.
