280x230mm Flexible Diamond Sandpaper Sheet for Glass, Stone & Ceramic

The 280x230mm Flexible Diamond Sandpaper Sheet is a standard full-size (11" x 9") industrial electroplated diamond abrasive sheet designed for manual hand block sanding, precision contouring, and fine edge beveling across glass, stone, porcelain, and ceramic materials.

Key Features

• Standard Full-Sheet Format (280x230mm / 11" x 9"): Industry-standard dimension easily cut into half-sheets, quarter-sheets, or custom shapes for handheld sanding blocks and precision mandrels.
• Precision Electroplated Diamond Coating: Sharp, uniformly distributed synthetic diamond crystals deliver fast cutting performance, consistent scratch uniformity, and long service life without grain shedding.
• Flexible Waterproof Backing: Reinforced cloth substrate flexes smoothly over convex facets, curved edges, and concave shapes without cracking or tearing.
• Wet & Dry Compatibility: Optimized for wet sanding with water coolant for dust suppression and maximum longevity, while supporting dry touch-up polishing.

Recommended Applications

• Manual edge breaking, seaming, and arris finishing on art glass, mirrors, and stained glass.
• Contour grinding, pre-polishing, and girdle refinement on agate, jasper, jade, and quartz cabochons.
• Deburring and surface blending on porcelain tiles, ceramics, granite, and marble tile edges.

Operating Guidelines

• Use with running water or frequent water dipping to maintain cool operating temperatures and prevent slurry buildup.
• Rinse clean after use and allow to air dry completely before flat storage.
