Norton 66261131623 Sanding Sheet 500 Grit Aluminum Oxide

Product Description

The NORTON 66261131623 is a 500-grit, extra fine aluminum oxide sanding sheet designed for precision finishing work across a range of trades and industrial applications. Built on a B-weight paper backing with an open coat density, this sheet resists loading and stays cutting longer than closed-coat alternatives. The aluminum oxide abrasive delivers consistent scratch patterns and controlled material removal at fine grit levels, making it suitable for surface prep, sealer sanding, and final finish passes on wood, metal, and composite materials. Weighing 0.03 pounds per sheet, it is part of the Norton A275 Series.

This sanding sheet is intended for dry use only and is not waterproof. The open coat construction makes it well-suited for applications where soft materials, sealers, or primers tend to load and clog abrasive surfaces quickly. Typical applications include furniture finishing, cabinet making, light metalwork, drywall finishing, and general surface preparation where a fine, controlled scratch pattern is required. It is used by finish carpenters, painters, auto body technicians, and maintenance trades who need repeatable results at the final stages of a surface prep workflow.

Key Features

• 500 grit aluminum oxide abrasive for extra fine material removal and consistent scratch patterns
• Open coat density resists loading, extending sheet life on soft or resinous materials
• B-weight paper backing balances flexibility and durability for hand sanding and pad use
• Dry use rated — not waterproof, optimized for dry sanding operations
• Load resistant construction reduces clogging on sealers, primers, and soft substrates
• Part of the Norton A275 Series for consistent abrasive performance across the line

Compatibility

Designed as a general-purpose dry sanding sheet compatible with standard hand sanding blocks and pad sanders that accept sheet-format abrasives. Verify sheet dimensions against your sanding tool before ordering.

Installation Notes

Secure the sheet firmly to the sanding block or pad before use to prevent slipping and uneven wear. Always sand in the direction of the grain on wood surfaces to avoid cross-grain scratches at fine grit levels. Inspect the sheet frequently and replace when abrasive loading or glazing reduces cutting efficiency. Dry use only — do not use with water or liquid lubricants.
