Ingco 50-Piece Multi-Grit Sanding Sheet Set (90mm x 231mm) - Premium Aluminum Oxide Hook & Loop Sandpaper Kit for 1/3 Sheet Orbital Sanders

Tackling large-scale restoration projects, smoothing down extensive drywall patches, or stripping weathered layers of old paint by hand is slow, exhausting work that often leaves an uneven finish. Low-grade sandpaper only adds to the frustration by tearing easily, losing its abrasive grit under pressure, or clogging within minutes of starting. The Ingco 50-Piece Multi-Grit Sanding Sheet Set is an industrial-grade surface preparation solution engineered to deliver rapid material removal and highly consistent finishes. Precision-cut to a universal 90mm x 231mm (3-35/64" x 9-3/32") footprint, this comprehensive master pack provides tradespeople and refinishing experts with a massive supply of high-end sheets to keep power sanders running efficiently without frequent trips to the tool store.

The exceptional service life and consistent scratch patterns of these sheets stem from their premium industrial-grade aluminum oxide abrasive grain formulation. This highly durable mineral grain resists extreme thermal buildup and fractures cleanly during use to continuously expose fresh cutting edges. Outfitted with a heavy-duty hook-and-loop backing matrix, each sheet grips your sander’s pad tightly without sliding, wrinkling, or lifting at the corners, even under heavy down-pressure. Spanning four strategically curated grits from coarse P40 for aggressive stripping to fine P180 for smooth pre-finish leveling, this ultra-versatile assortment mounts seamlessly onto matching 1/3-sheet orbital finishing sanders to streamline work across multiple material types.
