Tianli Metal Polishing pad:

Strong cutting and leveling: The metal bond firmly locks the diamond particles, providing exceptional grinding force. It is primarily used to quickly level uneven stone or concrete surfaces, remove deep scratches, old coatings, glue residue, or burn marks caused by high temperatures.

Deep grinding: In the restoration process, it acts as the “base layer” (rough grinding) to create a flat foundation for subsequent fine grinding and polishing (using resin pads). The grind feels rougher, but it is highly efficient.
