Norton 66261136589 Psa Disc 36 Grit 5 in Aluminum Oxide

Product Description

The NORTON 66261136589 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on metal, wood, and composite surfaces. Built on an X-weight cloth backing, this disc handles the flex and tension demands of heavy stock removal without tearing or delaminating. The aluminum oxide abrasive grain is bonded across a 5-inch diameter disc at 36 grit, placing it in the very coarse grade range. That combination makes it well suited for weld blending, surface prep, and rapid paint or coating removal. Installers and fabricators mount these discs directly to PSA-compatible backup pads without additional hardware or fasteners.

This disc is used in industrial and trade fabrication environments where fast, aggressive cutting action is required. Typical applications include metal surface preparation before welding or coating, wood leveling in millwork and cabinetry, and paint stripping on structural steel or sheet metal. The maroon-colored disc is part of the R228 series and carries an X-weight cloth backing rated for high-tension grinding operations. No vacuum holes are present, so it is intended for solid backup pads without dust extraction ports. Sold individually, it fits into both production and service shop workflows.

Key Features

• 36-grit aluminum oxide grain delivers very coarse, high-speed stock removal
• X-weight cloth backing resists tearing under aggressive grinding pressure
• PSA mounting system attaches directly to compatible backup pads with no hardware
• Flexible construction allows the disc to conform to slightly contoured surfaces
• No vacuum holes — compatible with solid, non-perforated backup pads
• R228 series designation for consistent performance tracking across production use

Compatibility

Designed for use with standard 5-inch PSA backup pads and compatible right-angle grinders or disc sanders that accept PSA-mount abrasive discs. No vacuum-hole configuration; solid backup pads only.

Installation Notes

PSA discs are installed by a machinist, metal fabricator, or finishing technician using a compatible 5-inch PSA backup pad. Power down and disconnect the grinder or sander before mounting or removing the disc. Press the disc firmly and evenly onto the backup pad to ensure full adhesive contact before running the tool. Inspect the disc before each use for edge lifting, tears, or delamination and discard any disc showing visible damage.
