Norton 66261131505 Psa Disc 400 Grit 6 in Aluminum Oxide 100pk

Product Description

The NORTON 66261131505 is a pressure-sensitive adhesive (PSA) abrasive disc designed for fine surface finishing and preparation work. Built on a B-weight paper backing, this disc uses aluminum oxide abrasive grain rated at 400 grit, placing it in the super fine grade range. It measures 6 inches in diameter and includes 6 vacuum holes for dust extraction during use. The flexible backing conforms to slightly contoured surfaces, making it suitable for both hand-sanding blocks and random orbital or disc sanders used in finishing applications. Each package contains 100 discs.

This disc is used in woodworking, metalworking, auto body preparation, and general surface refinishing where a super fine finish is required before sealing, staining, or topcoating. The PSA backing adheres directly to a compatible hook-free foam or rubber backup pad. The 400 grit rating makes it appropriate for final smoothing passes, light stock removal between finish coats, or scuff-sanding painted surfaces. It fits standard 6-inch PSA backup pads with vacuum hole patterns that align with the 6-hole configuration of this disc.

Installation Notes

Disconnect or power down the sander before mounting or removing discs. Press the disc firmly and evenly onto the backup pad to ensure full adhesive contact before operation. Avoid exposing unused discs to moisture or extreme heat, as this can degrade the PSA adhesive layer. These discs are intended for use by woodworking professionals, auto body technicians, and finishing tradespeople familiar with abrasive tool operation.
