Norton 66261131494 Psa Sanding Disc 180 Grit 5 in

Product Description

The NORTON 66261131494 is a pressure-sensitive adhesive (PSA) sanding disc designed for surface finishing and material removal applications in fabrication, woodworking, and metalworking environments. Built on a B-weight paper backing with aluminum oxide abrasive, this disc delivers consistent cut and finish at 180 grit, placing it in the very fine grade range. Each pack contains 100 discs at 5 inches in diameter. The flexible construction and lightweight backing make it well-suited for orbital and random-orbit sanders used by machinists, fabricators, and finishing tradespeople.

This disc is intended for use on wood, metal, and composite surfaces where a controlled, fine finish is required. The PSA backing mounts directly to foam or hard backup pads without clamps or clips, reducing changeover time on production floors and service calls. Five vacuum holes are included to support dust collection when used with compatible sanding machines, improving visibility and surface clarity during use. The A275 series designation reflects a general-purpose aluminum oxide construction suited to a wide range of finishing tasks.

Designed as an OEM-style replacement or standard consumable for 5-inch PSA backup pads used with orbital and random-orbit sanders equipped with dust collection ports matching a 5-hole pattern.

Installation Notes

Installation is performed by fabricators, machinists, or finishing tradespeople using standard PSA-compatible backup pads. Before mounting, ensure the backup pad surface is clean and free of adhesive residue from prior discs to ensure full contact and secure adhesion. Power down and disconnect the sander before changing discs. Do not exceed the RPM rating of the backup pad being used with these discs.
