CONSTANT TORQUE & HIGH EFFICIENCY: Powered by a high-end 350W AC brushless motor. Unlike brushed sanders, this professional tool maintains constant speed under heavy load. The motor does not "bog down" or sag even when leaning on it hard, ensuring 30% faster material removal. VIRTUAL ZERO VIBRATION: Engineered with precision counterweight balance for incredibly smooth operation. It significantly reduces arm fatigue and tingling hands, making it a "game changer" for woodworkers, carpenters, or users with carpal tunnel who work for long hours. 3/16" ORBIT FOR SCRATCH-FREE FINISH: The 5.0mm (3/16-inch) random orbit path prevents repeating sanding marks. Combined with 5-level variable speeds (4000-10,000 RPM), it easily delivers a mirror-smooth finish without annoying pigtails or scratches. ADVANCED DUST COLLECTION SYSTEM: Includes a 2M spiral-lock vacuum hose and multi-spec connectors to fit most Shop Vacs. The highly efficient dust extraction captures over 90% of debris, extending sandpaper life and keeping your workshop clean and healthy. COMPLETE PRO KIT & WARRANTY: Comes with 6" hook-and-loop pad, 12 Pcs assorted sandpapers (Purple & Red), wrench, and a 3 Meter power cord. We offer a 6-month full replacement policy to ensure your professional productivity.
