Norton 662611-36372 Psa Disc Roll 3.5 in P220B 100/roll

Product Description

The NORTON 662611-36372 is a PSA (pressure-sensitive adhesive) disc roll designed for hand sanding and orbital sanding applications across automotive, woodworking, and finishing trades. Each roll contains 100 pre-cut aluminum oxide coated abrasive discs measuring 3.5 inches in diameter with no center hole. The discs use a B-weight anti-loading paper backing and carry a P220B grit rating, placing them in the very fine category suited for finish sanding, surface prep between coats, and light stock removal on cured finishes. Cases ship with 4 rolls, giving technicians and shop operators a practical bulk supply for high-volume sanding work.

These PSA disc rolls are well suited for body shops, cabinet shops, and finishing operations where consistent fine-grit abrasive performance is required. The P220B grit is a common choice for scuff sanding primer, smoothing clear coats, and final prep before paint or lacquer application. The peel-and-stick backing makes disc changes fast on compatible PSA pad tools, reducing downtime during production sanding runs.

Key Features

• Aluminum oxide abrasive mineral for consistent, long-lasting cut on wood, metal, and painted surfaces
• B-weight anti-loading paper backing resists premature glazing during finish sanding
• P220B very fine grit for final prep, scuff sanding, and between-coat smoothing
• 3.5-inch diameter, no-hole design compatible with standard PSA sanding pads
• 100 discs per roll format simplifies inventory and disc dispensing at the workstation
• A275OP series construction for coated abrasive performance in production environments

Compatibility

Designed for use with 3.5-inch PSA sanding pads and backing plates on random orbital and straight-line sanders that accept pressure-sensitive adhesive discs with no center hole.

Installation Notes

Ensure the sanding pad surface is clean and free of old adhesive residue before applying each disc to achieve a secure bond. Press the disc firmly onto the PSA pad from the center outward to eliminate air pockets. Discs should be stored in a cool, dry location to preserve adhesive integrity. Follow all applicable shop safety guidelines including eye protection and dust collection when sanding.
