Norton 66261100245 Sanding Sheet 180 Grit Aluminum Oxide

Product Description

The NORTON 66261100245 is a dry-use abrasive sanding sheet coated with aluminum oxide grain on an A-weight paper backing. Rated at 180 grit, it falls in the very fine grade range, making it suited for finish sanding, light stock removal, and surface prep before sealing or coating. The open coat density reduces loading on softer materials, extending usable sheet life. This sheet runs dry only and is not waterproof. It is part of the Series A212 line of coated abrasives.

This sanding sheet is used in general-purpose hand sanding and finishing applications across woodworking, metalworking, and surface preparation trades. The very fine 180 grit is commonly applied in final-pass sanding on wood surfaces, between coats of finish, or for light deburring on metal. The A-weight paper backing provides flexibility for contour work while maintaining enough body for flat surface sanding. It is suitable for use by finish carpenters, cabinetmakers, and general contractors performing prep work.

Compatibility

Designed as a standard coated abrasive sanding sheet for use with hand blocks and compatible flat-bed sanding applications requiring a very fine 180 grit finish pass.

Installation Notes

Sanding sheets should be installed on a sanding block or holder with the abrasive face outward and the backing seated flat to prevent tearing. Always sand with the grain on wood surfaces when using fine-grit sheets to avoid cross-grain scratches. Wear appropriate respiratory protection when sanding, as fine dust from wood, metal, or coatings may present an inhalation hazard. Inspect sheets for loading or clogging before each use and replace when abrasive performance degrades.
