• Designed by Experts — Proven AtoRock Quality: Developed by a U.S.-based team with over 10 years of rock tumbling experience, AtoRock focuses exclusively on building reliable, professional tumblers. With a proven lineup from A1 (entry-pro model), A1 Pro (dual-barrel tumbler) to A3 (22lb heavy duty rock tumbler), every machine is rigorously tested and refined to meet the demands of serious hobbyists, collectors, and workshops—not casual or disposable use.
• Industrial-Grade Brushless Motor — Up to 3× Longer Lifespan: The brushless design eliminates carbon brushes and dust buildup, dramatically extending motor lifespan. Rated for up to 40,000 hours, it offers up to 3× the service life of traditional brushed motors—ideal for users who run their tumbler frequently or continuously.
• Extra-Large 22 lb Single Barrel — Up to 10× Higher Polishing Efficiency: The 22 lb extra-large barrel allows polishing up to 10× more material per cycle, reducing batch frequency while handling larger stones with ease. Reinforced construction with six metal twist knobs ensures secure sealing and stability during high-volume operation.
• Real-Time Motor Output & Runtime Display (Exclusive Feature): An exclusive digital display shows total tumbling days, extra hours, and real-time watt output, allowing you to monitor motor load at any time. Even under full load, typical daily energy consumption stays below 0.5 kWh, making long-term heavy-duty tumbling both powerful and cost-efficient.
• Full Metal Heavy-Duty Construction — Maximum Stability, Reduced Vibration: Built with a reinforced all-metal base and metal-clad barrel, the rigid structure minimizes vibration and maintains stability during extended operation. Compared to plastic-bodied tumblers, this design delivers superior durability and consistent polishing results over years of heavy use.
