• Industrial-Grade Brushless Motor – Built to Last Over 10 Years: Unlike ordinary rock tumblers, the KomeStone G3 model rock tumbler uses a verified brushless motor—stable, powerful, and tested by over 1 million units. Delivers long-term reliability and reduces noise by up to 67%.The tumbler rotates at approximately 40-50 RPM. The exact speed depends on the load; for example, it runs at about 48 RPM when the barrel is two-thirds full.
• Smart Control Panel with Real-Time Watt Tracking: Our exclusive 3-screen display shows total tumbling days, extra hours, and live power usage. The smart timer helps you optimize runtime, keeping typical daily energy consumption under 0.5 kWh—perfect for calculating costs and planning your polishing cycles with precision.
• Extra-Large 22LB Capacity for Serious Tumbling: Polish up to 10X more rocks per run. The reinforced barrel with 6 metal twist knobs makes loading and sealing easy — even during high-volume polishing. Built for collectors, workshops, and advanced users.
• Full Metal Build – Base + Drum Shell for Stability & Strength: Engineered with a durable metal base and a metal-clad drum for maximum durability. No plastic here—just solid construction that resists cracks, warping, and wear from long-term, heavy-duty use.
• 5-Year Warranty + Lifetime Support from KomeStone: KomeStone G3 rock tumbler comes with a 5-year warranty covering free replacement of the motor and other core components. All customers also receive lifetime technical support and access to replacement parts, including belts, barrels, metal lids, and the base.
