Norton 662611-31521 Speed-grip Paper Disc A275 P500B

Product Description

The NORTON 662611-31521 is a Speed-Grip abrasive paper disc engineered for surface preparation and finishing work. Built on the A275 backing type, this disc measures 3 inches in diameter with no hole configuration, making it compatible with backup pads that use Speed-Grip hook-style attachment systems. The P500B grit rating places this disc in the fine finishing range, suited for tasks such as seam leveling, primer sanding, and surface refinement before topcoat application. Each order is packaged in a bulk quantity of 50 discs. Licensed tradespeople and production finishers in automotive, woodworking, and metal fabrication environments are the primary users of this product.

This disc is designed for use in high-production surface finishing applications where consistent cut rate and finish quality are required. The 3-inch format fits compact orbital and random-orbit sanders common in automotive bodywork and furniture refinishing. The no-hole design suits backup pads without vacuum ports. P500B grit is appropriate for finish sanding between coats, denibbing cured paint or clear coat, and preparing surfaces for polishing compounds. These discs are packaged in a 50-count bulk quantity suitable for shop use.

Installation Notes

These discs are installed by trade finishers, automotive body technicians, and woodworking professionals. Before changing discs, power down and disconnect the sander from its power source or air supply. Press the disc firmly onto a clean, dry Speed-Grip backup pad to ensure full contact across the hook interface. Inspect the backup pad surface regularly for worn hooks, as a degraded pad reduces disc holding force and can cause disc separation during use.
