Norton 66261131477 Psa Disc Roll 6in P180 Aluminum Oxide 100pk

Product Description

The NORTON 66261131477 is a PSA sanding disc roll from the A275 OP series, designed for orbital and disc sander applications where pressure-sensitive adhesive mounting is required. Each roll contains 100 discs cut to 6 inches in diameter and loaded with aluminum oxide abrasive at a P180 fine grit. The open-coat configuration resists loading, making it effective on wood, painted surfaces, and light composites. The B-weight paper backing provides flexibility without sacrificing support under moderate sanding pressure. Tear resistance helps discs hold up during normal use and removal from the backup pad.

This disc roll suits woodworking shops, finishing contractors, and tradespeople who run high-volume sanding operations and need consistent, cost-effective abrasive media. The PSA backing bonds directly to a matching foam or rubber PSA backup pad, eliminating the need for hook-and-loop fasteners. The 6-inch diameter fits standard random orbital and single-disc sanders commonly found in cabinet shops, millwork operations, and finishing stages of construction work. The non-vacuum design means the disc surface is unperforated, which suits applications where dust collection is handled externally or where an uninterrupted abrasive face is preferred.

Key Features

• P180 fine grit aluminum oxide abrasive for controlled material removal and surface prep
• Open-coat construction resists loading on resinous or painted surfaces
• Pressure-sensitive adhesive backing for quick, secure pad attachment
• B-weight paper backing balances flexibility and backing support
• 100 discs per roll for extended production use
• Tear-resistant construction for reliable disc removal without backing failure

Compatibility

Designed for use with 6-inch PSA backup pads on random orbital sanders and disc sanders requiring a non-vacuum, pressure-sensitive adhesive disc in the fine grit range.

Installation Notes

Installation is performed by pressing the adhesive face of the disc firmly onto a clean, dry PSA backup pad. Ensure the backup pad surface is free of debris or residual adhesive before applying each new disc. Discs should be removed and replaced when abrasive loading or glazing reduces cutting efficiency. No tools or power shutoff procedures are required for disc changes, but the sander should be stopped completely before swapping discs.
