Norton 66261136714 Psa Disc 15 in 50 Grit Aluminum Oxide

Product Description

The NORTON 66261136714 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on large surface areas. Measuring 15 inches in diameter, this coarse-grade disc uses aluminum oxide abrasive bonded to an X-weight cloth backing for durability under heavy grinding loads. The PSA mount allows fast disc changes on compatible 15-inch random orbital or disc sanders. At 50 grit, this disc is suited for rapid stock removal, weld blending, and initial surface preparation before progressing to finer grits. It belongs to the R228 series and is flexible enough to conform to slightly contoured surfaces.

This disc is intended for use in industrial, manufacturing, and fabrication environments where large-format surface grinding is required. Typical applications include metal fabrication shops, woodworking operations, and finishing floors or composite panels. The X-weight cloth backing handles the mechanical stress of high-pressure grinding without tearing, making it a practical choice for production-level work. Licensed tradespeople and shop technicians working with floor grinders or large disc sanders are the primary installers and operators of this abrasive.

Key Features

• 15-inch diameter PSA disc for fast mounting and removal on compatible sanders
• 50 grit coarse aluminum oxide abrasive for aggressive stock removal
• X-weight cloth backing provides high tensile strength under heavy grinding pressure
• Flexible construction allows moderate conformability to contoured workpieces
• No vacuum holes — suited for solid-platen or non-vented disc applications
• Part of the R228 series for consistent performance across Norton abrasive product lines

Compatibility

Designed for use with 15-inch PSA-compatible random orbital sanders, disc grinders, and floor grinding machines that accept pressure-sensitive adhesive abrasive discs with no vacuum holes.

Installation Notes

Ensure the sander platen is clean and free of adhesive residue before mounting the disc to achieve a secure bond. Power down and disconnect the sander from its power source before changing discs. Press the disc firmly and evenly onto the platen from the center outward to eliminate air pockets. Dispose of worn discs per shop or facility waste guidelines, and do not exceed the maximum RPM rating of the sanding equipment in use.
