Porous Dry Sanding Discs are highly efficient abrasive consumables for automotive bodywork, woodworking, metal surface finishing, and other applications. Their core value lies in high cutting power, clog-resistant pores, and compatibility with mainstream pneumatic/electric grinders.

• Unique green abrasive formula for sharper cutting: Utilizes high-quality green aluminum oxide abrasive. Compared to standard brown fused alumina, green abrasive offers superior hardness and self-sharpening properties, delivering stronger and longer-lasting cutting power. Particularly suited for processing hard metal and wood surfaces.
• Innovative cyclone-hole design for ultimate clog prevention: Scientifically distributed holes create efficient airflow channels. During grinding, dust is rapidly drawn away like a cyclone, effectively preventing hole blockage. This ensures the sander's dust collection system maintains peak efficiency, significantly enhancing grinding results and extending sandpaper lifespan.
• Beyond clog prevention, the cyclone hole design enhances airflow to rapidly dissipate heat generated during grinding. This effectively prevents workpiece surface scorching, discoloration, or stress deformation due to overheating—making it ideal for precision grinding of temperature-sensitive materials like aluminum, plastics, and delicate components.

1. Automotive Repair & Detailing: Used for coarse and medium grinding of automotive body filler, removing old paint layers, and pre-polishing new paint surfaces. The cyclone vent design effectively handles heavy dust generated during automotive painting.
2. Metal Processing: Suitable for rust removal, deburring, brushing, and surface polishing of metals like stainless steel, aluminum, and copper. The green abrasive's high cutting power easily handles hard metal surfaces.
3. Woodworking & Furniture Manufacturing: Used for wood sanding, deburring, primer sanding before painting, and topcoat polishing. The cyclone vent design prevents wood dust clogging, maintaining a clean wood surface.
4. Plastic & Composite Processing: Suitable for surface treatment of various plastics, fiberglass, and other composites. The cyclone vent's heat dissipation effectively prevents plastic melting or deformation due to overheating.

1. Always inspect the sander's dust collection system before use to ensure the cyclone port's clog-prevention function is operational.
2. Select appropriate grit size based on workpiece material and sanding requirements. Excessively coarse grit may damage surfaces, while overly fine grit reduces efficiency.
3. Wear safety goggles and a dust mask during grinding to prevent dust and debris from harming your eyes and respiratory tract.
4. Store sandpaper in a dry, cool place away from direct sunlight and moisture to maintain optimal performance.
5. Do not use sandpaper for tasks beyond its design specifications, such as on high-speed rotating cutters, to avoid hazards.
