3" Dry Diamond Polishing Pads — Compact Size for Tight Edges & On-Site Work
Our 3" Dry Diamond Polishing Pads are engineered for on-site dry polishing where water is not an option. The compact 80mm format reaches tight countertop edges, sink cutouts, and curved profiles where 4" pads can't fit. 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.

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.
What is the difference between CUST-18 (3" single grit) and CUST-07 (3" 4-Step system)?
CUST-18 is sold by individual grit — ideal for contractors who need to replace specific grits or buy in bulk for one stage. CUST-07 is a pre-packaged 4-step progressive system (50→100→200→400) for shops that want a complete kit.

Frequently Asked Questions
Why use a 3" pad instead of a 4" pad?
The 3" (80mm) format fits tighter spaces — sink cutouts, inside corners, narrow countertop edges, and curved profiles where a 4" pad is too large. For open flat surfaces, 4" pads are more efficient.
How to use 3" dry diamond polishing pads on stone?
Run at 2,000–4,500 RPM with light to moderate pressure. Keep the pad moving — do not dwell in one spot. Start with Grit 50 for scratch removal, progress through to Grit 3000 for mirror finish. Always wear a P100 respirator for dry polishing.
Are granite and concrete polishing pads different?
Yes. Concrete pads use a harder bond matrix for abrasive concrete surfaces. Granite and marble pads use softer resin bonds. CUST-18 is a medium-soft bond suitable for both stone and light-duty concrete dry polishing.
