Norton 66261131509 Psa Sanding Disc 240 Grit 6 in

Product Description

The NORTON 66261131509 is a pressure-sensitive adhesive (PSA) sanding disc engineered for surface finishing and material removal on a wide range of substrates. At 240 grit, it falls in the very fine grade range, making it suited for finish sanding, light stock removal, and surface preparation before sealing or coating. The disc features an aluminum oxide abrasive bonded to a B-weight paper backing, which provides a balance of flexibility and durability under moderate sanding pressure. Each disc measures 6 inches in diameter and includes 6 vacuum holes for dust extraction during use. The pack contains 100 discs.

This disc is designed for use with PSA-compatible random orbital and rotary sanders fitted with 6-inch platens. Typical applications include wood finish sanding, composite surface prep, light metal finishing, and between-coat sanding in automotive and woodworking environments. The very fine 240 grit is commonly used as a final pass before applying stain, primer, or clear coat. The flexible paper backing conforms to slightly contoured surfaces, making it useful for both flat panels and mildly curved workpieces. The A275 series designation indicates a general-purpose finishing formulation.

Installation Notes

Installation is performed by hand — peel the release liner and press firmly onto a clean, dry PSA sanding platen to ensure full adhesion. Ensure the sander is powered off and unplugged before changing discs. Align vacuum holes with the platen ports before applying pressure to seat the disc. Discs that have lost adhesion or loaded with material should be replaced to maintain consistent finish quality.
