Norton 66254497792 Psa Disc 5 in 220 Grit Aluminum Oxide

Product Description

The NORTON 66254497792 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing, sanding, and prep work across metal, wood, and composite materials. At 5 inches in diameter with a 220 very fine grit aluminum oxide abrasive, this disc delivers controlled material removal and smooth surface refinement. The cloth backing with an X-weight construction provides flexibility and durability under load, making it suited for contour sanding and flat surface work. It belongs to the Norton R228 series and is installed by metalworkers, woodworkers, fabricators, and finishing technicians using PSA-compatible backup pads.

This disc is used in both shop and field finishing applications where a PSA mounting system is in place. The 220 grit rating makes it appropriate for fine finishing passes, pre-finish prep, and light stock removal on wood, painted surfaces, and soft metals. The flexible cloth backing allows the disc to conform slightly to curved or irregular surfaces, reducing gouging and uneven stock removal. No vacuum holes are included, so it is intended for solid backup pads without dust extraction ports.

Compatibility

Designed for use with 5-inch PSA (sticky-back) backup pads on random orbital sanders, disc sanders, and angle grinders equipped with a PSA pad. No specific compatible model numbers were provided in the product data.

Installation Notes

Disconnect the sander from its power source before changing discs. Peel the liner from the adhesive backing and press the disc firmly and evenly onto a clean, dry PSA backup pad to ensure full adhesive contact. Avoid mounting on backup pads with vacuum holes, as the solid cloth backing is not perforated. Worn or contaminated backup pads reduce adhesion and disc performance; inspect the pad surface before each disc change.
