Norton 66261136555 Psa Disc 3 in 80 Grit Aluminum Oxide

Product Description

The NORTON 66261136555 is a pressure-sensitive adhesive (PSA) abrasive disc designed for grinding, blending, and surface preparation tasks on metal, wood, and composite materials. Built on an X-weight cloth backing, the disc delivers firm support and flexibility, making it well suited to both flat and contoured surfaces. The 80-grit aluminum oxide abrasive mineral provides consistent, moderate stock removal across a range of substrates. The PSA mount allows fast disc changes on compatible backup pads without tools. Licensed tradespeople and skilled finishers install and use this disc in production and maintenance environments.

This disc fits residential and light commercial applications wherever a 3-inch PSA backup pad is used. Typical scenarios include weld blending on metal fabrications, paint removal, rust abatement, and surface conditioning before coating. The R228 series cloth-backed construction handles higher contact pressure than paper-backed alternatives, making it a practical choice for metalworking benches, portable angle grinders with PSA pads, and drill-mounted applications. No vacuum holes are present, so it is not intended for dust-extraction sanding systems.

Installation Notes

Disconnect or de-energize the tool before mounting or removing the disc. Align the disc concentrically on a clean, dry PSA backup pad and press firmly from center outward to ensure full adhesive contact. Inspect the disc for tears, loading, or glazing before each use and replace if damaged. Follow applicable ANSI B11 and tool-manufacturer guarding requirements when operating powered abrasive tools.
