Belt-Free Direct-Drive Motor: This rock tumbler kit uses a low-voltage direct-drive motor for smoother, more efficient polishing without belt transmission, eliminating belt wear and replacement while reducing maintenance costs. It runs at ≤35 dB, letting you enjoy a quiet and comfortable creative experience

Even Polishing Results: This rock polishing kit uses advanced techniques to ensure smooth, rounded surfaces after polishing, letting every stone reveal its unique luster. Suitable for both beginners and enthusiasts, it makes polishing easy and fun. NOTE: rough stones are NOT included and need to be prepared separately

Flexible Adjustment: Our stone tumbler features a 1- to 9- day timer and 4 speed levels ranging from 75 RPM to 120 RPM, meeting polishing needs for different materials and stages. With overload protection and power-off memory, it automatically resumes the remaining cycle after outages. The constant-speed design ensures more uniform and consistent results
