Norton 66261131508 Psa Disc 280 Grit 6 Inch 100 Pack

Product Description

The NORTON 66261131508 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for surface finishing applications requiring very fine material removal. Built on a B-weight paper backing, this disc uses aluminum oxide abrasive at 280 grit, placing it in the very fine grade category. The PSA mounting system allows fast disc changes on compatible backing pads without mechanical fasteners. Each disc measures 6 inches in diameter and includes 6 pre-cut vacuum holes to support dust extraction during use. The pack contains 100 discs. This product belongs to the A275 series and is suited for use by finish carpenters, auto body technicians, metal fabricators, and other trades requiring controlled fine-finish grinding or sanding.

These discs are designed for dry sanding and finishing operations on wood, painted surfaces, and light metals. The flexible paper backing conforms to slightly contoured surfaces, making them useful for both flat-panel work and mild profile sanding. The 6-inch diameter fits standard 6-inch PSA backing plates commonly found in orbital and rotary finishing tools equipped with dust collection ports. The 6-hole vacuum hole pattern aligns with compatible dust-extraction pads to keep the work surface clear and extend disc life.

Installation Notes

Ensure the backing pad surface is clean and free of debris before applying the PSA disc to achieve full adhesive contact. Power down and disconnect the sander from its power source before changing discs. Align the vacuum holes on the disc with the holes on the backing pad to maintain dust extraction performance. Discs should be stored flat and away from heat sources to preserve adhesive integrity.
