Norton 66261131621 Sanding Sheet 800 Grit Aluminum Oxide

Product Description

The NORTON 66261131621 is an 800-grit aluminum oxide sanding sheet designed for ultra-fine finishing work on a range of surfaces. Rated ultra fine grade, this sheet uses aluminum oxide abrasive, one of the most common and durable abrasive minerals for general-purpose dry sanding applications. It features a B-weight paper backing, which balances flexibility and tear resistance for flat or lightly contoured surfaces. The open coat density helps resist loading, keeping the sheet cutting cleanly through successive passes. This product is intended for dry use only and is suitable for woodworking, metal finishing, and surface prep tasks where a fine, smooth finish is the target.

The 66261131621 is built for dry sanding applications in woodworking shops, manufacturing environments, and trade finishing work. It belongs to the Norton A275 series, which is designed for fine finishing passes on bare wood, sealers, primers, and light metals. This sheet is well suited for finish carpenters, cabinet makers, and surface preparation professionals who need consistent scratch patterns at ultra-fine grits before final coating or polishing steps.

Installation Notes

Secure the sheet firmly to the sanding block or tool platen before use to prevent slipping. Inspect the sheet before each use and replace when abrasive loading or glazing reduces cutting performance. This product is rated for dry use only — do not use with water, oils, or wet sanding applications. Safe handling practices apply when sanding materials that produce fine dust; use appropriate respiratory protection per OSHA guidelines.
