4" Metal Bond Diamond Polishing Pads for Granite Marble Terrazzo | 50-200 Grit — KAIYI

4" Metal Bond Diamond Polishing Pads — Marble, Granite, Ceramic & Terrazzo | KAIYI

⚠️ Usage Note: This series is designed for surface grinding and coarse polishing. For a high-gloss mirror finish, follow up with resin-bond polishing pads.

KAIYI 4-inch metal bond diamond polishing pads deliver aggressive, consistent cutting power on marble, granite, ceramic tile, terrazzo, and engineered stone. The sintered metal bond matrix ensures long service life and stable performance across a wide range of hard surface materials.

Key Features:

• Sintered Metal Bond: High cutting efficiency on hard materials including granite, ceramic, and terrazzo.
• Wide Material Compatibility: Marble, granite, ceramic tile, terrazzo, engineered stone, and concrete.
• Extended Service Life: Metal bond construction significantly outlasts resin alternatives under equivalent grinding conditions.
• Heat-Resistant: Engineered to withstand friction from heavy-duty grinding without glazing.
• Hook & Loop Backing: Compatible with all standard 4" angle grinders. Fast pad change system.
• Wet Use Recommended: Water cooling maximizes diamond exposure and extends pad life.

Technical Specifications:

Grit Selection Guide:

• Grit 50 — Extra Coarse: Heavy stock removal, deep scratch elimination, surface leveling on hard stone and ceramic.
• Grit 100 — Coarse: General grinding and surface preparation. Removes saw marks and moderate surface irregularities.
• Grit 200 — Medium: Refining after coarse grinding. Prepares surface for resin bond polishing pads.

Usage Tips

• Maintain continuous water flow — prevents glazing and maximizes diamond exposure.
• Apply moderate pressure and let the diamonds do the work. Excessive pressure accelerates wear.
• For ceramic and porcelain: start at Grit 100 to avoid over-aggressive material removal.
• Follow up with resin bond pads (Grit 400–3000) for high-gloss mirror finish.
• Inspect pad under raking light between grit stages before advancing.

Technical FAQ

Can metal bond pads produce a polished finish?
Metal bond pads are for grinding and surface preparation (Grit 50–200). For a high-gloss mirror finish, follow up with resin bond polishing pads after the grinding stage.

Do I need water when using metal bond pads?
Yes. Water cools the sintered matrix, prevents glazing, and maximizes diamond exposure for consistent cutting performance.

Are these pads compatible with standard angle grinders?
Yes. The hook & loop (Velcro) backing is compatible with all standard 4-inch angle grinders with a flexible backing plate.

Frequently Asked Questions

What is a metal bond diamond polishing pad?

Metal bond diamond pads use sintered metal matrix to hold diamond particles. Unlike resin bond pads, metal bond pads are designed for aggressive grinding, lippage removal, and surface leveling — not final polishing. Use 30-400 grit for stock removal, then switch to resin bond for finishing.

How to use metal bond diamond polishing pads on granite?

Start 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 moving with moderate pressure. After grinding with metal bond, switch to resin bond pads (200-3000 grit) for the polishing stages.

How to polish marble with diamond pads?

Metal bond pads can be used for initial marble grinding (50-100 grit) if there is deep damage. For standard marble polishing, start with resin bond pads at 100-200 grit. Always use wet method for marble — dry heat can cause thermal shock and cracking.

How to polish terrazzo with diamond pads?

Start with 50 or 100 grit metal bond diamond pads for aggressive grinding and leveling of terrazzo surfaces. Progress to 200 grit, then switch to resin bond pads from 400 to 3000 grit for the final polish. Wet method recommended throughout.

How to use diamond polishing pads?

Start with the coarsest grit and work through progressively finer grits. Keep the pad moving at all times. Use light to moderate pressure — let the diamonds do the work. Clean the surface between grit changes.

How to clean diamond polishing pads?

Rinse pads with clean water after each use. Use a soft brush to remove slurry. For metal bond pads, a stiff brush is acceptable. Air dry completely before storing. Replace when the diamond layer is worn below 1mm.

How to use diamond hand polishing pads?

Diamond hand pads are used for edge profiling, seam blending, and detail work. Hold the pad flat against the surface with consistent pressure. Start with coarser grits and work through to finer grits.
