Norton 66261131624 Sanding Sheet 400 Grit Aluminum Oxide

Product Description

The NORTON 66261131624 is a 400-grit aluminum oxide sanding sheet designed for fine finishing work across a range of surfaces. Rated extra fine grade with a B-weight paper backing, this sheet delivers consistent material removal and a smooth finish on wood, metal, and painted surfaces. The open-coat design reduces loading and extends sheet life during dry sanding applications. It is part of the Norton A275 series, a line built for general-purpose hand and orbital sanding tasks performed by woodworking professionals, painters, and finishing trades.

This sanding sheet is suited for dry finishing applications where a smooth, refined surface is required before final coating or polishing. The open coat construction helps prevent clogging when sanding softer materials or finish coats. Load-resistant properties make it appropriate for use on materials that tend to gum up standard abrasive sheets. It is used in both production shop environments and field finishing work where consistent fine-grit abrasion is needed.

Installation Notes

This product is installed by securing the sheet to a compatible sanding block or orbital sander pad according to the tool manufacturer's instructions. Ensure the workpiece surface is clean and free of loose debris before sanding. This sheet is rated for dry use only — do not use with water or liquid lubricants. Dispose of worn sheets promptly, as degraded abrasive can cause uneven surface finish.
