Norton 662611-55374 Sanding Disc 6 in A975 P320B Grit

Product Description

The NORTON 662611-55374 is a 6-inch pressure-sensitive adhesive (PSA) sanding disc designed for surface finishing and stock removal applications. Part of the A975 product line, this disc features a P320B grit rating, placing it in the fine-grit range well suited for finish sanding, scratch refinement, and surface preparation before coating or sealing. The no-hole design keeps the disc profile clean for use on backing pads without vacuum ports. These discs are sold individually and are intended for professional tradespeople and shop technicians working with orbital and rotary sanders in high-volume finishing environments.

These PSA sanding discs are applicable across a range of professional finishing tasks including woodworking, metal fabrication, automotive bodywork, and composite surface prep. The P320B fine grit makes them a go-to choice for final-stage sanding passes where surface smoothness and coating adhesion are the priority. The 6-inch format is a standard size compatible with many benchtop and handheld sanding platforms used in trade and production shop settings.

Installation Notes

Clean the backing pad surface thoroughly before applying the PSA disc to ensure full adhesion and prevent premature release during operation.
