Norton 66261131612 Psa Sanding Disc 220 Grit 8 in

Product Description

The NORTON 66261131612 is a pressure-sensitive adhesive (PSA) sanding disc designed for flat surface stock removal and finishing work. Part of the A275 series, this disc measures 8 inches in diameter and cuts with 220-grit aluminum oxide abrasive, placing it in the very fine grade range. The paper backing is B-weight, which balances flexibility and durability for orbital and disc sander applications. Each package contains 100 discs. Installation and use are handled by machinists, fabricators, woodworkers, and finishing tradespeople working on flat or lightly contoured surfaces.

These PSA discs are suited for finish sanding applications on wood, painted surfaces, and light metal prep. The self-adhesive backing attaches directly to a foam or hard PSA-compatible backup pad without fasteners or hook-and-loop interfaces. The A275 series is commonly used in production finishing environments where consistent scratch patterns and grit uniformity matter across a high volume of pieces. No vacuum holes are included, so these discs are intended for solid backup pads without dust-extraction ports.

Key Features

• 220-grit aluminum oxide abrasive for very fine finish sanding
• 8-inch diameter fits standard PSA backup pads of the same size
• B-weight paper backing provides flexibility for flat and mildly contoured surfaces
• Pressure-sensitive adhesive mount — no hook-and-loop required
• No vacuum holes — designed for solid backup pad use
• 100 discs per package for production volume work

Compatibility

Designed for use with PSA-compatible 8-inch backup pads on standard orbital and disc sanders. No specific machine model compatibility was stated in the product data.

Installation Notes

Ensure the backup pad surface is clean and free of debris before applying the PSA disc, as contamination will reduce adhesion. Peel the liner and center the disc over the backup pad before pressing firmly from the center outward. Discard discs that show loading, tearing, or loss of adhesion to avoid uneven scratch patterns. Do not use these discs on backup pads with dust-extraction holes, as the absence of vacuum ports will block airflow and reduce dust collection efficiency.
