Norton 662611-42474 Sanding Disc 5 in A975 P220B Grit

Product Description

The NORTON 662611-42474 is a 5-inch pressure-sensitive adhesive sanding disc designed for surface preparation, finishing, and material removal on orbital and random-orbit sanders. Sold individually, this disc uses A975 film backing with a P220B grit designation, placing it in the fine-grit range suited for final sanding passes, sealer scuffing, and between-coat finishing work. The no-hole configuration makes it compatible with solid backup pads where dust extraction is not routed through the disc face. Woodworkers, auto body technicians, painters, and finishing contractors are the primary users of this disc type.

This disc is applicable to flat and low-contour surfaces where a fine finish is required before coating or clear-coat application. The A975 film-backed construction provides consistent cut and a flexible substrate that conforms slightly to the work surface, reducing chatter and deep scratch patterns. Typical applications include furniture finishing, cabinetry, automotive primer scuffing, and composite surface prep in both residential shop and light commercial environments.

Key Features

• 5-inch diameter fits standard 5-inch orbital and random-orbit sander backup pads
• A975 film backing for consistent cut and durability across finishing passes
• P220B fine grit for final sanding, sealer scuffing, and between-coat finishing
• No-hole disc design compatible with solid backup pads
• Pressure-sensitive adhesive (PSA) attachment for quick disc changes

Compatibility

Designed as an OEM-style replacement disc for 5-inch PSA backup pads used on standard orbital and random-orbit sanders with no center dust-extraction port.

Installation Notes

Installation is performed by hand — peel the liner from the PSA backing and press the disc firmly onto a clean, dry 5-inch backup pad. Ensure the backup pad surface is free of adhesive residue from previous discs before applying a new one, as contamination reduces bond strength. Power down and unplug the sander before changing discs. Dispose of worn discs in accordance with local shop waste practices.
