Norton 662611-31541 Speed-grip Paper Disc A275 P320B 5 in

Product Description

The NORTON 662611-31541 is a Speed-Grip pressure-sensitive adhesive paper disc engineered for machine sanding on wood, composites, paint, and primers. Built on an A275 paper backing, this disc delivers consistent cut and finish at P320B grit, making it a go-to choice for fine-finishing and between-coat sanding passes. The 5-inch diameter with no hole configuration fits standard PSA backup pads where dust extraction is not required or is handled by a separate shroud. These discs are sold in a bulk pack of 400, suited for production shops, body technicians, and finishing contractors who burn through abrasives at volume.

This disc is used in automotive refinishing, furniture manufacturing, cabinetry, and general woodworking applications where a fine, consistent scratch pattern is needed before topcoat application. The P320B grit classification indicates a fine abrasive grade appropriate for scuff sanding sealers, smoothing grain filler, and final surface prep before staining or painting. The no-hole design makes it compatible with solid backup pads used on random orbital and rotary sanding tools in both shop and field settings.

Compatibility

Designed for use with 5-inch solid PSA backup pads on random orbital and rotary sanders in automotive, woodworking, and finishing applications. No specific model compatibility was provided in the product data.

Installation Notes

PSA discs are applied by pressing firmly onto a clean, dry backup pad surface. Remove the release liner and align the disc to the pad before pressing down to ensure full adhesion. Discs should be replaced when cutting performance drops noticeably or when the abrasive surface shows glazing. Follow all tool manufacturer guidelines and applicable shop safety codes when operating pneumatic or electric sanders.
