Unlike resin bond pads, metal bond pads are designed for\n  aggressive grinding, lippage removal, and surface leveling — not final polishing. Use 30-400 grit for stock removal, then switch to resin\n   bond for finishing.\u003c\/p\u003e\n\n\u003ch3\u003eHow to use metal bond diamond polishing pads on granite?\u003c\/h3\u003e\n\u003cp\u003eStart with 30 or 50 grit metal bond pads for aggressive granite leveling and lippage removal. Run wet at 3,000-4,500 RPM. Keep the pad\n   moving with moderate pressure. After grinding with metal bond, switch to resin bond pads (200-3000 grit) for the polishing stages.\u003c\/p\u003e\n\n\u003ch3\u003eHow to polish marble with diamond pads?\u003c\/h3\u003e\n\u003cp\u003eMetal bond pads can be used for initial marble grinding (50-100 grit) if there is deep damage. For standard marble polishing, start\n  with resin bond pads at 100-200 grit. Always use wet method for marble — dry heat can cause thermal shock and cracking.\u003c\/p\u003e\n\n\u003ch3\u003eHow to polish terrazzo with diamond pads?\u003c\/h3\u003e\n\u003cp\u003eStart with 50 or 100 grit metal bond diamond pads for aggressive grinding and leveling of terrazzo surfaces. Progress to 200 grit,\n  then switch to resin bond pads from 400 to 3000 grit for the final polish. Wet method recommended throughout.\u003c\/p\u003e\n\n\u003ch3\u003eHow to use diamond polishing pads?\u003c\/h3\u003e\n\u003cp\u003eStart with the coarsest grit and work through progressively finer grits. Keep the pad moving at all times. Use light to moderate\n  pressure — let the diamonds do the work. Clean the surface between grit changes.\u003c\/p\u003e\n\n\u003ch3\u003eHow to clean diamond polishing pads?\u003c\/h3\u003e\n\u003cp\u003eRinse pads with clean water after each use. Use a soft brush to remove slurry. For metal bond pads, a stiff brush is acceptable. Air\n  dry completely before storing. Replace when the diamond layer is worn below 1mm.\u003c\/p\u003e\n\n\u003ch3\u003eHow to use diamond hand polishing pads?\u003c\/h3\u003e\n\u003cp\u003eDiamond hand pads are used for edge profiling, seam blending, and detail work.
