Norton 662611-31612 Sanding Disc 8in A275 P220B Grit 4 Pack

Product Description

The NORTON 662611-31612 is an 8-inch pressure-sensitive adhesive sanding disc designed for surface preparation and finishing applications across woodworking, metalworking, and general fabrication work. Built to the A275 specification, this disc uses a P220B grit designation, placing it in the fine-grit range suited for final-pass smoothing, paint prep, and light stock removal. The no-hole disc format is compatible with solid backup pads and random-orbit or disc sanders that do not rely on through-hole dust extraction. Sold in a minimum quantity of 4 discs per order, these discs are a standard supply item for shops and field crews running high-volume sanding operations.

These discs are used across residential and commercial job sites wherever consistent fine-grit finishing is required. Typical applications include furniture and cabinet finishing, drywall feathering, metal deburring, and automotive body prep work. The 8-inch diameter fits standard 8-inch disc sander platens and backup pads. The PSA backing allows quick disc changes without mechanical fasteners, reducing downtime between passes. Minimum order quantity is 4 discs.

Installation Notes

Ensure the backup pad surface is clean and free of adhesive residue before applying a new disc. Press the disc firmly from the center outward to eliminate air pockets and ensure full adhesive contact. Operate sanding equipment within the RPM rating printed on the disc or packaging. Worn or loaded discs should be removed promptly to avoid heat buildup and surface damage.
