Norton 66261183818 Psa Disc 150 Grit 6 in Aluminum Oxide

Product Description

The NORTON 66261183818 is a PSA (pressure-sensitive adhesive) abrasive disc engineered for use with random orbital sanders in material stock removal and surface finishing applications. This 6-inch disc is built on a B-weight paper backing with an aluminum oxide abrasive layer rated at 150 grit, placing it in the very fine grade range. The yellow disc operates at up to 15,000 RPM and offers flexible construction that conforms to contoured work surfaces. Installers, fabricators, and finishing tradespeople use this disc where controlled material removal and surface prep are required ahead of coating or inspection.

This disc is suited for residential and light commercial shop applications involving wood, metal, or composite surfaces that require fine finishing passes. The PSA mount allows quick disc changes on compatible random orbital sanders without fasteners or hook-and-loop backing. This disc does not include vacuum holes, making it appropriate for sanders used without dust extraction or where hole pattern compatibility is a concern. It is part of the Norton A296 series.

Key Features

• 6-inch diameter PSA disc with pressure-sensitive adhesive backing for tool-free mounting
• 150 grit aluminum oxide abrasive rated very fine grade for controlled surface finishing
• B-weight paper backing provides flexibility and conforms to curved or contoured surfaces
• Rated up to 15,000 RPM for compatibility with standard random orbital sander speeds
• No vacuum holes — compatible with solid-platen random orbital sanders
• Norton A296 series construction for consistent abrasive performance across the disc surface

Compatibility

Designed for use with random orbital sanders that accept 6-inch PSA-mount abrasive discs with no vacuum holes. Verify platen size and adhesive-mount compatibility with your specific sander model before use.

Installation Notes

Ensure the sander is powered off and unplugged before removing a spent disc and mounting a new one. Clean the platen surface of adhesive residue before applying a fresh PSA disc to ensure full contact and prevent vibration or premature release during use. Allow the disc to seat firmly against the platen before engaging the tool. Do not exceed the rated 15,000 RPM maximum speed.
