850x290mm Flexible Diamond Sandpaper Sheet for Glass, Stone & Ceramic

The 850x290mm Flexible Diamond Sandpaper Sheet is an extra-long industrial electroplated diamond abrasive blanket engineered for stroke sanders, long platen hand sanders, and wide-area manual surface processing across glass, natural stone, porcelain, and ceramic materials.

Key Features

• Extended 850x290mm (33.5" x 11.4") Dimension: Extra-long sheet format offers generous working length for wide stroke sanding blocks, continuous platen wrapping, or custom cutting into custom discs, strips, and belts.
• High-Density Electroplated Diamond Coating: Sharp synthetic diamonds uniformly distributed across the surface provide rapid stock removal, smooth scratch consistency, and long service life without grain shedding.
• Flexible & Tear-Resistant Cloth Backing: Reinforced waterproof substrate conforms smoothly to broad convex radii and large flat beds without tearing or cracking.
• Wet & Dry Versatility: Fully waterproof backing supports wet sanding with water coolant for dust suppression and extended diamond longevity, while supporting quick dry touch-ups.

Recommended Applications

• Edge breaking, seaming, and fine arris finishing on architectural glass, mirrors, and stained glass installations.
• Manual cabochon smoothing, facet touch-ups, and girdle polishing on agate, jade, jasper, and quartz slabs.
• Smoothing and beveling sharp edges on ceramic and porcelain tiles.

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.
