Product Performance
Variable-Speed Operation: Three selectable speeds of 4,500 / 6,500 / 8,500 RPM provide adjustable rotational performance for cutting, grinding, polishing, and finishing applications.
High Torque Output: Maximum torque of 3.0 N·m supports stable material removal and surface processing on steel, iron, pipes, and other metal components.
Direct-Drive Performance: The direct-drive configuration reduces conventional gear transmission components, helping provide efficient power transfer and more stable spindle operation during continuous use.
125mm Disc Compatibility: Designed for standard 125mm / 5-inch cutting discs, grinding wheels, and flap discs, providing a suitable working platform for general metal fabrication and maintenance tasks.
Cordless Power System: The 37V / 3.0Ah battery provides 111Wh of stored energy for cable-free operation, while the 1.8 kg net weight supports easier handling during mobile and elevated work.
Applications
Metal Fabrication & Cutting: The 125 mm disc and high-speed rotation are suitable for cutting structural steel, iron pipes, and high-strength alloys.
Surface Grinding & Chamfering: The M14 spindle supports material removal, weld smoothing, surface grinding, and edge chamfering.
