3" Dry Diamond Polishing Pads for Stone & Concrete — Factory Direct
Our 3" Dry Diamond Polishing Pads are engineered for on-site dry polishing where water is not an option. Available in Grit 50 to 3000 for a complete sequence from aggressive stock removal to mirror finish on granite, marble, quartz, concrete, and terrazzo.
⚠️ Note on Segment Styles: We produce several segment patterns (Honeycomb, Spiral, Triangle). Styles are shipped based on availability. If a specific pattern is required, please note in your order or contact us.
Key Features:
- Heat-Resistant Resin Bond: Formulated for dry use. Prevents surface burning and color bleeding on light-colored stones including marble and quartz.
- High Diamond Concentration: Grade A industrial diamonds for consistent cutting performance across the full grit range.
- Efficient Dust Management: Varied segment geometries (Honeycomb/Spiral) eject dust and debris quickly, reducing clogging.
- Full Grit Range: Grit 50 to 3000 for the complete polishing sequence.
- 3" Compact Format: Ideal for tight countertop edges, sink cutouts, and curved profiles.
- Hook & Loop Backing: Fits all standard 3" angle grinders and polishers.

Usage Tips
- Hard granite / quartz: Start at 2,000–2,500 RPM with Grit #50. Keep the pad moving to prevent heat buildup.
- Soft marble / limestone: Use 1,500–2,000 RPM with light pressure for scratch-free results.
- Concrete (light duty): Dry mode suitable for surface restoration; for heavy concrete grinding, wet pads are recommended.
Technical FAQ
Can these dry pads be used with water?
These pads are optimized for dry use. For wet applications, see our dedicated wet polishing pad range.
Will dry polishing leave burn marks?
Keep the pad moving at all times and avoid excessive pressure. The heat-resistant resin bond and segment geometry are designed to dissipate heat and protect delicate stone surfaces.

Frequently Asked Questions
What to use to polish stone surfaces?
Diamond polishing pads are the professional standard for stone fabrication. Use wet diamond pads (grit 50-3000) with a variable-speed polisher for granite, marble, and concrete. For on-site work, dry diamond pads with honeycomb cooling design require no water.
How to use diamond polishing pads?
Start with the coarsest grit (50 or 100) and work through progressively finer grits (200 → 400 → 800 → 1500 → 3000). Keep the pad moving at all times. Use light to moderate pressure — let the diamonds do the work. Run at 3,000-6,000 RPM depending on grit. Clean the surface between grit changes.
Where to buy diamond polishing pads?
Diamond Pads Factory (KAIYI) offers factory-direct diamond polishing pads with wholesale pricing. No middleman markup. Free samples for qualified B2B buyers. Ships globally from Quanzhou, Fujian, China.
Do you use water with diamond polishing pads?
Wet diamond polishing pads require water for cooling and dust control. Dry diamond polishing pads are designed with honeycomb segments for air cooling and require no water. Check your pad type before use.
How to clean diamond polishing pads?
Rinse pads with clean water after each use to remove stone slurry. For resin bond pads, avoid aggressive brushing. Allow pads to air dry completely before storage. Replace pads when the diamond layer is worn below 1mm.
What are the best diamond polishing pads?
The best diamond polishing pads depend on your application. For granite — high-temperature resin bond. For marble — non-staining white bond. For concrete — metal bond for grinding, resin bond for polishing. KAIYI offers OEM customization.
What pad do you use to polish concrete floors?
For concrete floors: metal bond diamond pads (30-100 grit) for aggressive grinding and lippage removal, then transition to resin bond pads (200-3000 grit) for polishing. KAIYI offers both metal and resin bond concrete polishing pads.
How to diamond polishing pads for concrete floors?
Start with 30 or 50 grit metal bond pads on a floor grinder for surface preparation. Progress through 100 → 200 grit with metal bond. Switch to resin bond pads at 200-400 grit for honing. Apply concrete densifier after 400 grit. Continue polishing 800 → 1500 → 3000 grit with resin pads.
Are granite and concrete polishing pads different?
Yes. Concrete pads typically use a harder bond matrix designed for abrasive concrete surfaces. Granite pads use softer resin bonds optimized for hard natural stone. Concrete polishing often requires metal bond pads for the initial grinding stages.
How to use dry diamond polishing pads?
Run at 3,000-6,000 RPM with light to moderate pressure. The honeycomb segments draw in air for cooling — keep the pad moving, do not dwell in one spot. Allow the pad to cool between passes. Break in new dry pads on scrap stone. Always wear P100 respirator.
Can you use wet polishing pads dry?
No. Wet diamond polishing pads rely on water for cooling. Using them dry will cause rapid heat buildup, pad delamination, and stone damage. If you need dry capability, use KAIYI dry diamond polishing pads with honeycomb cooling design.
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. Use wet for best results on granite and marble.
How to clean polishing pads by hand?
Rinse thoroughly with clean water immediately after use. Use a soft brush to gently remove stone slurry. Air dry completely before storing. Do not stack wet pads together.
