4" Premium 3-Step Diamond Polishing Pads for Granite — Model 36 | Wet & Dry — KAIYI
$8.90 USD
Product Overview: KAIYI Model 36 (MPN: KAIYI-DPF-CUST-36) is an industrial-grade 4-inch 3-step diamond polishing pad system engineered for hard granite and quartzite fabrication. Utilizing Grade A+ synthetic diamonds in a high-temperature resin matrix with a 3.0mm wear layer, it consolidates traditional 7-step polishing into 3 progressive stages (Step 1 Coarse Prep, Step 2 Honing, Step 3 High Gloss) for wet or dry operation up to 3,500 RPM.
4" Premium 3-Step Diamond Polishing Pads (Model 36) — High-Efficiency Granite Fabrication
The KAIYI Model 36 (CUST-36) 4-inch 3-step diamond polishing pads are designed specifically for stone fabricators working on hard, dense granite, quartzite, and engineered stone. While standard multi-grit pads often glaze or burn when pushed on abrasive granite minerals, Model 36 features an elevated concentration of sharp diamond micro-crystals and a thermal-dissipating resin bond. It provides aggressive stock removal and refined gloss development across three sequential discs, reducing tool changes and finishing time by over 40%.
Key Performance Advantages:
- Formulated for Dense Granite: Specialized bond hardness prevents segment loading and glazing on quartz- and feldspar-rich granites.
- True 3-Step Sequential Polish: Step 1 removes saw marks and levels surface lippage; Step 2 refines scratches into a uniform satin hone; Step 3 produces deep color depth and specular mirror clarity.
- Wet & Dry Versatility: Advanced multi-channel heat evacuation enables reliable dry edge profiling on jobsites (2,000–3,000 RPM) or continuous wet polishing in fabrication shops.
- Non-Staining Resin Matrix: White/translucent resin formulation prevents chemical bleeding, scorching, or discoloration on white and light-veined granites.
- Heavy-Duty 3.0 mm Wear Layer: Substantial diamond concentration ensures long working life and high square-footage coverage per disc.
- Universal Fit: Standard heavy-duty hook-and-loop Velcro backing fits all 4" (100mm) flexible backer pads on variable-speed angle grinders and polishers.

Step-by-Step Polishing Workflow:
- Step 1 (Coarse Prep / Scratch Removal): Removes bridge saw marks, edge lippage, and heavy machining scratches. Run at 2,500–3,000 RPM with moderate, flat downward pressure.
- Step 2 (Honing / Semi-Gloss): Erases abrasive tracks from Step 1, closing stone pores and producing an even satin honed finish. Rinse slurry between steps.
- Step 3 (Final Buff / Optical Clarity): Activates ultra-fine micro-diamonds to achieve a rich, deep specular reflection and full natural color saturation without topical waxes.

Frequently Asked Questions (FAQ)
How does a 3-step diamond pad achieve high gloss without intermediate grits?
Model 36 utilizes engineered multimodal diamond distributions in each step. Step 1 combines coarse cutting diamonds with intermediate abrasive points; Step 2 refines the profile directly into a pre-polish; Step 3 utilizes ultra-fine micro-diamonds to produce high specular gloss in a single finishing pass.
Can Model 36 be used completely dry on granite jobsites?
Yes. Model 36 features deep segment distribution channels that dissipate frictional heat quickly. When dry polishing, keep machine speed between 2,000 and 3,000 RPM and avoid excessive localized pressure.
What is the difference between Model 36 and Model 34?
Model 36 is a 3-step rapid polishing set optimized for maximum speed on straight countertop edges. Model 34 is a 5-step super flexible system with cobblestone segmentation designed specifically to wrap around curved bullnose profiles and undermount sink cutouts.
