Norton 66261131626 Sanding Sheet 320 Grit Aluminum Oxide

Product Description

The NORTON 66261131626 is an aluminum oxide sanding sheet rated at 320 grit, classified as extra fine grade. It uses a B-weight paper backing with an open coat density, making it suited for dry sanding applications where clogging resistance matters. The sheet belongs to Norton's A275 series and is load resistant, helping it maintain cutting performance longer during finish sanding work. This sheet is installed and used by trade professionals, woodworkers, and finishers who need consistent, controlled material removal at fine grit levels for surface prep and finishing passes.

This sanding sheet is designed for dry use on wood, paint, primers, fillers, and similar substrates where a fine surface finish is required. The open coat construction reduces loading when sanding soft or resinous materials. It is a practical choice for cabinet finishers, flooring contractors, auto body technicians, and general trades professionals performing final prep work before coating or painting. It is not rated for wet or waterproof applications and should be used dry only.

Installation Notes

This sheet is used by finishers, woodworkers, and trades professionals for hand or machine sanding. Ensure the sander or sanding block is powered off and unplugged before loading or changing sheets. Use dry only — do not apply water, solvents, or lubricants to the sheet during use. Inspect the sheet before use and replace when abrasive loading or wear reduces cutting effectiveness.
