Norton 66261136587 Psa Disc 5 in 50 Grit Aluminum Oxide

Product Description

The NORTON 66261136587 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for aggressive stock removal on a wide range of substrates. Built on an X-weight cloth backing, it delivers the rigidity and durability needed for demanding grinding and finishing operations. The aluminum oxide abrasive cuts at 50 grit, placing it firmly in the coarse grade range — well suited for rapid material removal, weld blending, and surface preparation before finer finishing steps. The flexible construction conforms to slightly contoured workpieces, and the PSA mount makes disc changes fast on compatible backup pads. This disc is part of the Norton R228 series.

This disc is used in metalworking, fabrication, and woodworking shops where high-rate surface conditioning is required. At 5 inches in diameter, it fits standard 5-inch PSA backup pads used on random orbital sanders and disc grinders. Typical applications include deburring, rust and scale removal, weld seam blending, and preparatory surface grinding ahead of coating or finishing. No vacuum holes are present, making it a solid-face disc appropriate for backup pads without dust-extraction ports.

Designed for use with standard 5-inch PSA backup pads on random orbital sanders and disc grinders. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation and disc changes should be performed with the tool powered off and unplugged or locked out per applicable safety procedures. Ensure the backup pad surface is clean and free of debris before pressing the PSA disc firmly into place for full adhesive contact. Inspect the disc for cuts, tears, or delamination before each use and remove from service if damage is found. Abrasive disc use should follow ANSI B7.7 or equivalent safety standards applicable to coated abrasive products.
