30-3000 Grit Diamond-Polishing Pads Wet/Dry Flexible For Granite Marble Polishing
4-Inch Wet Diamond Polishing Pad is a professional-grade tool optimized for wet sanding and polishing. Its semi-flexible design ensures superior adaptability for both flat surfaces (e.g., countertops) and contoured areas. With a full grit range (50–3000) plus a buffing pad, it covers all processing stages from rough prep to high-gloss finishing. Boasting aggressive cutting power and exceptional durability, it works seamlessly with low-speed wet grinders/polishers, leveraging wet operation to deliver consistent, high-quality results every time.

Adopt a gradient polishing process: start with a low-grit pad (50 or 100 grit) to remove deep scratches, then switch to a 3000-grit pad for the final polishing stage.
First attach the polishing pad to a backing pad, then secure the assembled backing pad and polishing pad to the polishing machine.
Do not exceed the maximum speed range of 4,000–4,500 RPM. Use slow, overlapping movements during operation to prevent the pad from getting stuck.
After changing polishing pads between grit stages, clean the work surface thoroughly to remove any leftover abrasive particles.
