Grinding includes the steps from the lowest starting grit, which depends on the concrete (typically 30 or 50 grit), up to 120 grit. Grinding diamonds usually are metalbond or brazed tools for lippage removal and floor leveling, or pcd tools for coating and glue removal. Depending on the bonding material, metal abrasives have different hardness which determines how diamonds are exposed.
