Powerful, reliable motor: 1280W pure copper motor provides steady, torque for efficient sanding and grinding on drywall, ceilings, and concrete floors. Low operating noise and multiple heat dissipation holes reduce overheating and extend motor life for safer, longer use. Precise speed control: Sixstep adjustable speed from 40 to 300 RPM using a corded switch. Finetune RPM for delicate drywall finishing or more aggressive concrete grinding to match different materials and site conditions. Ergonomic handling for extended use: Twohandle layout with a 90° adjustable secondary handle improves balance and control while reducing operator fatigue. The design supports longer work periods without sacrificing accuracy. Fast, flexible sanding head: Selfadhesive sanding discs allow quick pad changes on site. The 360° rotating disc reaches corners and edges easily, making it simpler to finish tight areas and transition between surfaces. Durable construction: Made from metal, plastic, and aluminum alloy to resist rust, wear, and heat. Smooth surfaces and a simple structure make cleaning and maintenance straightforward while protective vents safeguard the motor. Compatibility and function: Suited for drywall sanding, ceiling and wall finishing, and concrete surface grinding—works across construction, renovation, and industrial environments, including wall industry projects and mining site maintenance. Use scenarios 1) Drywall finishing: Remove joint compound and smooth walls and ceilings quickly before painting, using lower RPM for a fine finish. 2) Concrete floor prep: Grind small spots and rough patches before applying coatings or leveling compounds, increasing speed for more aggressive material removal. 3) Industrial maintenance: and maintain concrete or masonry surfaces in warehouses, manufacturing sites, or mining facilities where durable, sustained performance is required.
