Norton 66261122792 Psa Disc 9 Inch 150 Grit Aluminum Oxide

Product Description

The NORTON 66261122792 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing, stock removal, and prep work on wood, metal, and composites. Built on a heavyweight X-weight cloth backing, this disc delivers the flexibility and durability needed for contoured and flat surface applications. The 150-grit aluminum oxide abrasive is rated very fine grade, making it well-suited for finish sanding passes and surface smoothing before coating or sealing. At 9 inches in diameter, it mounts directly to PSA-compatible backup pads without additional hardware. This disc is part of the NORTON R228 series.

This disc is used in woodworking shops, metal fabrication, and general surface preparation environments. It is suited for both bench-mounted disc sanders and portable units equipped with PSA backup pads. Typical applications include final sanding of wood panels, light metal deburring, and prep work ahead of primer or topcoat application. The flexible cloth backing allows the disc to conform slightly to irregular surfaces, reducing the risk of gouging on softer substrates. No vacuum holes are included, making this disc appropriate for solid backup pads without dust extraction ports.

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive disc for 9-inch PSA-compatible disc sanders and backup pads used in woodworking, metalworking, and general surface preparation applications.

Installation Notes

Installation is performed by removing the release liner and pressing the PSA disc firmly onto a clean, dry 9-inch backup pad. Ensure the backup pad surface is free of debris or residual adhesive before mounting to achieve full contact and even wear. Power down and disconnect the sander from its power source before changing discs. Discard worn discs that show exposed backing, uneven abrasive wear, or loss of adhesion.
