Norton 66261183810 Psa Disc Roll 180 Grit 5 in 100 Discs

Product Description

The NORTON 66261183810 is a PSA (pressure-sensitive adhesive) disc roll loaded with 100 pre-cut 5-inch aluminum oxide abrasive discs on paper backing. Rated at 180 grit, this is a very fine grade abrasive suited for finish sanding, light material removal, and surface prep work before sealing or coating. The B-weight paper backing provides a balance of flexibility and support, allowing the disc to conform to slightly contoured surfaces without tearing. At a maximum speed rating of 15,000 RPM, the roll is designed for use on random orbital sanders in production and finishing environments. Installers, fabricators, and finishing tradespeople will find the roll format convenient for high-volume sanding operations.

This disc roll is intended for use on random orbital sanders in both shop and field settings. The 180-grit aluminum oxide formula is well-suited for wood, painted surfaces, and light metal finishing where a smooth, consistent scratch pattern is required before final coating. The PSA backing allows quick disc changes without additional adhesives. No vacuum holes are included, making these discs appropriate for sanders without dust-port configurations or for open sanding applications where dust collection is handled separately. The yellow disc color aids in quick visual identification during use.

Installation Notes

Disc installation requires no tools — peel the liner and press the PSA face firmly onto a clean, dry sanding pad to ensure full adhesion before operation. Confirm the sander pad is free of debris or adhesive residue from previous discs before applying a new disc. Do not exceed the 15,000 RPM maximum speed rating. Disc replacement should be performed with the sander powered off and unplugged.
