Norton 66261131613 Psa Disc 180 Grit 8 in 100 Pack

Product Description

The NORTON 66261131613 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing and material removal on a wide range of substrates. Part of the A275 Series, this disc features aluminum oxide abrasive at 180 grit, placing it in the very fine grade range for smooth finish work. The B-weight paper backing provides flexibility during use, allowing the disc to conform to slightly contoured surfaces. Each order includes 100 discs, making this a production-ready supply for shops with consistent sanding demand. Installed by machinists, woodworkers, metalworkers, and surface prep technicians.

This disc is suited for both production and finishing applications in shop environments. The 8-inch diameter fits PSA-compatible backing pads on stationary or random-orbital sanders. At 180 grit, it is appropriate for final material blending, seam smoothing, paint prep, and light stock removal. The aluminum oxide abrasive delivers consistent cut and durability across wood, painted metal, and composite surfaces. No vacuum holes are included, so this disc is intended for solid backing pad configurations without dust extraction ports.

Designed for use with PSA-compatible 8-inch backing pads on stationary sanders and random-orbital sanders configured for adhesive-mount discs. No specific model compatibility was provided in the product data.

Installation Notes

Mounting is performed by peeling the protective liner and pressing the disc firmly onto a clean, dry PSA backing pad. Ensure the backing pad surface is free of dust, adhesive residue, and debris before applying a new disc to maintain full contact and prevent disc detachment during operation. Always power down and de-energize the sander before disc changes. Discard discs showing tears, glazing, or loss of abrasive — do not continue use on a worn disc.
