3" 4-Step Dry Diamond Polishing Pads — Complete Kit for On-Site Stone & Concrete
Our 3" 4-Step Dry Diamond Polishing Pads consolidate the traditional 7-step sequence into four stages, engineered specifically for on-site dry polishing where water is not an option. The compact 3" (80mm) format fits tight countertop edges, sink cutouts, and curved profiles. Suitable for granite, marble, quartz, and concrete.
Key Features:
- 4-Step Dry System: Fewer pad changes vs a 7-step sequence. Designed for on-site countertop polishing, edge finishing, and indoor applications where water use is restricted.
- Heat-Resistant Resin Bond: Formulated for dry use. Prevents glazing and staining on light-colored stones including White Carrara marble and light quartz.
- High Diamond Concentration: Grade A industrial diamonds for consistent cutting performance across all four steps.
- 3" Compact Format: Ideal for tight countertop edges, sink cutouts, and curved profiles where a 4" pad is too large.
- Universal Hook & Loop Backing: Compatible with any standard 3" or 4" angle grinder.
4-Step Workflow:
- Step 1: Rough grinding and leveling — removes deep scratches and surface irregularities.
- Step 2: Honing and scratch removal — refines the surface to a smooth matte finish.
- Step 3: Pre-polishing — further smoothing in preparation for final buffing.
- Step 4: Final high-gloss buffing — achieves a mirror-like finish.

Usage Tips
- Hard granite: Keep RPM between 2,500–4,000. Let the diamonds do the work — excessive pressure shortens tool life.
- Soft marble / quartz: Use 1,500–2,500 RPM with light pressure to prevent surface scratching.
- Edges & contours: The 3" format is ideal for tight countertop edges, sink cutouts, and curved profiles.
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 on marble?
Keep the pad moving at all times and avoid excessive pressure. The heat-resistant resin bond is formulated to prevent glazing and staining on delicate light-colored stones.
What is the difference between CUST-07 (4-Step Kit) and CUST-18 (single grit)?
CUST-07 is a pre-packaged 4-step progressive system — ideal for shops that want a complete kit. CUST-18 is sold by individual grit, ideal for contractors who need to replace specific grits or buy in bulk for one stage.

Frequently Asked Questions
How to use a 4-step dry diamond polishing system on stone?
Start with Step 1 for rough grinding and scratch removal. Progress through Step 2 (honing), Step 3 (pre-polish), and Step 4 (mirror finish). Keep the pad moving at 2,500–4,000 RPM. Do not dwell in one spot — heat buildup is the main risk in dry polishing. Always wear a P100 respirator.
Can I use this 4-step kit on concrete?
Yes, for light-duty concrete surface restoration. For heavy concrete grinding or high-PSI concrete (5,000+ PSI), wet polishing pads with metal bond are recommended for the initial stages.
What is the difference between a 4-step and 7-step polishing system?
A 4-step system uses wider grit jumps between stages, which is faster but may leave faint scratch patterns on very soft or dark stone. For most granite, quartz, and concrete applications, 4-step delivers comparable results with fewer pad changes.
