DRY & WET SANDING FOR VERSATILE USE: Dry sanding quickly removes burrs and rough surfaces, while wet sanding, when used with water or lubricants, effectively reduces dust, minimizes friction heat, prevents clogging, and extends the sandpaper’s lifespan. It also ensures a smoother, more refined finish. QUICK INSTALLATION: Easy replacement, boosting work efficiency. Convenient hook-and-loop design, allowing for easy sandpaper replacement. Whether switching between different grits or quickly changing for various sanding tasks, it helps save valuable time and improve work efficiency. 4 TYPES OF ADAPTER RODS: 4 different shanks for different machines, making it compatible with various common sanding tools such as electric drills, angle grinders, and pneumatic sanders.
