Norton 66261180006 Sanding Sheet 320 Grit Aluminum Oxide

Product Description

The NORTON 66261180006 is an aluminum oxide sanding sheet designed for dry, hand or machine sanding applications where a fine surface finish is required. Rated at 320 grit with an extra fine grade, it delivers controlled material removal for final prep, light stock removal, and surface smoothing on wood, metal, and composite materials. The J-weight cloth backing provides flexibility and durability, allowing the sheet to conform to contoured surfaces without tearing. Closed coat construction keeps abrasive grains packed tightly across the surface for consistent scratch patterns throughout the life of the sheet. This is a dry-use abrasive and is not rated for wet sanding.

This sanding sheet is suited for finish sanding operations in woodworking, metal fabrication, automotive bodywork prep, and general surface conditioning. The extra fine 320 grit is most commonly used in final sanding stages before sealing, priming, or coating. The cloth backing makes it compatible with both hand sanding blocks and power sanders that accept sheet-style abrasives. It belongs to the Norton R243 series, which is positioned for industrial and trade use where consistent cut and finish quality are expected across repetitive tasks.

Installation Notes

Sheet abrasives are installed by trades including woodworkers, metal fabricators, and automotive technicians using hand blocks or sheet-style power sanders. Ensure the sanding surface and workpiece are free of debris before use. This sheet is rated for dry use only — do not use with water, oils, or solvents. Inspect the sheet for wear or loading before each use and replace when cut rate or finish quality degrades.
