4" Super Flexible 5-Step Diamond Polishing Pads (Model 34) — Specifically Engineered for Hard Granite

Our CUST-34 Super Flexible 4" 5-Step Diamond Polishing Pads are purpose-built for stone fabricators working on hard, dense granite, quartzite, and engineered stone. While standard multi-step pads are rigid and frequently glaze over or crack on tight curves, Model 34 combines high-grade industrial diamond crystals with an ultra-pliant, heat-resistant resin matrix. Featuring an advanced cobblestone segment pattern, this super flexible 5-step sequence (Step 0, Step 1, Step 2, Step 3, Step 4) effortlessly hugs bullnose profiles, ogee edges, and tight sink cutouts while delivering an exceptional factory-grade mirror finish.

Why Fabricators Choose Model 34 for Granite:

🌀 Super Flexible Contour Conformity: Cobblestone mosaic segmentation allows the pad to bend and flex smoothly around curved edges, bullnose profiles, and sink corners without segment delamination or edge biting.
💎 Engineered for Hard Granite: Formulated with a specialized matrix hardness and sharp Grade A+ diamond crystals designed to cut dense granite minerals without burning, glazing, or slowing down.
⚡ Progressive 5-Step System: Combines the rapid stock removal of multi-step grinding with the refined mirror depth of traditional 7-step sets—saving over 40% in labor and disc changes.
🔥 Wet & Dry Versatility: Performs reliably on-site for dry edge touch-ups (2,000–3,000 RPM) and in workshop fabrication with full water cooling.
🛡️ Non-Staining White Resin Bond: Zero color transfer, scorching, or chemical bleeding, making it safe for white, exotic, and light-veined granites.
⏳ Heavy-Duty 3.0 mm Wear Layer: Substantial diamond concentration ensures long service life and high square-footage coverage per disc.
🔄 Universal Fit: Standard heavy-duty hook-and-loop backing fits all 4" (100mm) flexible backer pads on handheld variable-speed polishers and angle grinders.

Step-by-Step Granite Polishing Workflow:

Step 0 (Surface Prep / Leveling): Aggressively flattens saw marks, levels surface lippage, and establishes a uniform foundation for progressive polishing.
Step 1 (Coarse Prep — Red): Removes coarse grinding patterns and shapes curved edge contours. Maintain consistent, moderate pressure.
Step 2 (Medium Honing — Cyan): Erases coarse abrasive scratches from Step 1, producing a smooth, uniform matte honed profile.
Step 3 (Fine Polishing — Yellow): Tightens stone pores, removes micro-swirls, and initiates deep color saturation and semi-gloss clarity.
Step 4 (Final Mirror Buff — Purple): Activates ultra-fine micro-diamonds to achieve a deep optical mirror reflection (94 GU) without chemical buffing compounds.

Fabrication Tips for Granite:

Curved Profiles: Use with a flexible rubber backer pad to allow the super flexible pad to wrap naturally around bullnose and ogee shapes.
Wet Polishing: Maintain constant water flow to flush granite slurry from the cutting interface and keep the diamond edges exposed.
Dry Edge Profiling: Keep machine RPM between 2,000 and 3,000 RPM. Avoid excessive pressure on edge profiles to prevent heat buildup.
