If you're running a stone fabrication shop, you've probably noticed that not all 3-step polishing systems are created equal. The Chido, EZ3, and Trio are three of the most popular 3-step diamond polishing pad systems on the market — and while they all get you from scratch removal to final polish in three passes, they're built for different shops, different materials, and different priorities.
Here's how to choose the right one. Polishing pads are the final step in the countertop fabrication sequence — for the full workflow context, see our How to Fabricate a Granite Countertop: Complete Shop Workflow. For edge-specific polishing after profiling, see our Stone Countertop Edge Profiles: Complete Fabricator's Guide.
What All Three Have in Common
Before we get into the differences, it's worth noting what these systems share:
- Hook & loop backing for use with standard angle grinders and hand polishers
- Wet use for optimal pad life and surface cooling
- 4" diameter, 4mm thickness
- Max RPM: 4,500
- Compatible with quartz, granite, quartzite, and engineered stone
If you need a fast, repeatable 3-step system for countertop fabrication, all three will get the job done. The question is which one fits your shop best.
Chido 4" 3-Step Diamond Polishing Pads by Tenax USA
Best for: Shops that want a proven hybrid formula from a trusted brand, especially on mixed material runs.
The Chido system is built by Tenax USA — one of the most recognized names in stone care chemistry. What sets Chido apart is its hybrid diamond formulation, which balances cutting speed with finishing quality across both light and dark stone surfaces. Paired with geometric water displacement technology, the Chido pads move water efficiently across the surface, preventing hydroplaning and keeping the diamonds in consistent contact with the stone.
Where Chido excels:
- Consistent performance across light and dark materials in the same production run
- Reliable results on quartz, marble, granite, and quartzite
- Backed by Tenax USA's formulation expertise
Consider Chido if: You run a mixed-material shop and need a pad that performs predictably across different stone types without swapping systems.

Weha EZ3 3-Step Diamond Polishing Pads
Best for: High-volume shops prioritizing speed and value on granite, quartz, and engineered stone.
The EZ3 is Weha's entry into the 3-step category, and it's built around one core promise: get through your polishing sequence fast without sacrificing finish quality. The pads are flexible, cut aggressively, and are especially effective on medium to light colored granite, quartz, and engineered stone.
For shops running high daily volume where cost-per-pad matters, the EZ3 delivers strong performance at a price point that makes sense for production environments.
Where EZ3 excels:
- Fast cutting action for high-throughput fabrication
- Flexible design handles profile work and edge polishing
- Strong value-to-performance ratio for daily shop use
Consider EZ3 if: You're running volume production on granite and quartz and want a reliable, cost-efficient system that keeps your line moving.

Weha Trio 3-Step Polishing Pads
Best for: Shops that demand premium finish quality, especially on dark materials, bowls, and complex profiles.
The Trio is Weha's flagship 3-step system, and it shows. Every design decision is engineered for finish quality and pad longevity. The Geometric Water Displacement Technology — Weha's exclusive geo pattern — channels water through the pad to prevent hydroplaning and keep diamonds biting consistently. The white hybrid resin bond won't bleed or leave marks on light or dark stone, and the 4mm full diamond matrix with rounded edges lets the pad glide into bowls, ogee edges, and tight inside corners without segment failure.
Where Trio excels:
- Superior finish on both light and dark quartz and engineered stone
- Flexible enough for bowls, ogees, and complex profiles
- Non-bleeding resin bond — safe on light-colored materials
- Long pad life due to full diamond matrix construction
Consider Trio if: You're doing high-end custom work, running dark quartz or engineered stone, or need a pad that can handle complex profiles without edge failure.
