Norton 66261131627 Sanding Sheet 280 Grit Aluminum Oxide

Product Description

The NORTON 66261131627 is an aluminum oxide sanding sheet engineered for dry, fine-finish abrading across a range of trade and shop applications. Rated at 280 grit in the extra fine grade category, it uses a B-weight paper backing that balances conformability with tear resistance. The open coat density reduces loading and extends sheet life on softer materials. Part of the NORTON A275 series, this sheet is designed for hand sanding and finishing work where surface smoothness and grit consistency are critical to the final result.

This sanding sheet is suited for finish sanding wood, metal, composites, and coated surfaces in residential and light commercial settings. Woodworkers, metal fabricators, painters, and general contractors commonly use 280 grit sheets for final preparation before topcoating or polishing. The dry-use construction and load-resistant abrasive layer make it a practical choice for between-coat sanding on paint and clear finishes, as well as light deburring and surface conditioning tasks. It is not rated for wet or wet-dry applications.

Installation Notes

Sanding sheets are installed by trades including finish carpenters, painters, metal fabricators, and general maintenance technicians. Secure the sheet firmly to a sanding block or pad to maintain even pressure and avoid uneven abrasion. Inspect the sheet regularly during use and replace when the abrasive surface becomes glazed or loaded. Do not use this sheet with water or liquid lubricants as it is rated for dry use only.
