Norton 662611-31538 Speed-grip Paper Discs 5in A275 P500B

Product Description

The NORTON 662611-31538 is a Speed-Grip hook-and-loop paper disc engineered for surface preparation and finishing applications. Measuring 5 inches in diameter with no center hole, these discs use an A275 aluminum oxide abrasive construction and carry a P500B grit rating, placing them in the fine-finishing range suited for sanding between coats, light stock removal, and surface smoothing. They are sold in bulk packs of 100 discs, making them practical for high-volume shop or jobsite use. Trades that rely on consistent finish quality, including auto body technicians, woodworkers, and general contractors, will find the Speed-Grip backing system provides fast disc changes without tools.

These discs are designed for use with 5-inch random orbital and orbital sanders equipped with a hook-and-loop (Speed-Grip) backing pad. The P500B grit designation follows the FEPA grading standard and indicates a fine abrasive appropriate for finish sanding on wood, primer, filler, and light metal surfaces. The no-hole configuration means dust extraction relies on the work surface or alternative collection methods rather than through-disc vacuum ports. Typical applications include production finishing environments, body shop prep work, and multi-coat finishing sequences where intermediate sanding is required.

Key Features

• A275 aluminum oxide abrasive construction for consistent cut and finish
• P500B FEPA grit rating suited for fine finishing and between-coat sanding
• 5-inch diameter, no-hole design for use with standard 5-inch hook-and-loop backing pads
• Speed-Grip hook-and-loop attachment system allows rapid disc changes
• Bulk pack of 100 discs reduces per-unit cost in high-volume applications

Compatibility

Designed for use with 5-inch random orbital or orbital sanders fitted with a hook-and-loop (Speed-Grip) backing pad. No specific model compatibility was provided by the manufacturer for this listing.

Installation Notes

Press the disc firmly onto the hook-and-loop backing pad before operating the sander to ensure full contact and prevent slipping. Inspect the backing pad surface for worn or damaged hooks before attaching a new disc, as a degraded pad reduces holding power and can affect finish quality. Operate the sander at the speed recommended for the workpiece material and abrasive grit to avoid burning or uneven stock removal. Dispose of worn discs when cutting performance drops noticeably, as continued use with a spent abrasive increases heat and surface damage risk.
