3M 7010510357 Sanding Sheet 20 Grit Aluminum Oxide

Product Description

The 3M 7010510357 is an aluminum oxide sanding sheet from the 3M 372L series, designed for dry abrasive finishing applications. The sheet uses an aluminum oxide abrasive bonded to a film backing, delivering consistent cut and durability across flat and contoured surfaces. At 20 grit, it falls in the extra fine grade range, making it suited for light material removal, surface prep, and finishing passes where a refined surface is the goal. At 0.02 pounds per sheet, it is lightweight and easy to handle. Licensed trade professionals and skilled finishers use this sheet for precision surface work in woodworking, metal prep, and composite finishing operations.

This sanding sheet is used in dry grinding and finishing applications. The film backing provides dimensional stability and resistance to tearing during use, which is useful when working on contoured surfaces or with backing pads. The 372L series is appropriate for tasks requiring controlled, fine abrasive action without the use of water or lubricating fluids. It is not rated for wet or waterproof applications. Typical use environments include production finishing lines, maintenance shops, and field surface preparation where dry abrasive work is required.

Installation Notes

Installation and use of abrasive sheets should follow the tool and pad manufacturer's guidelines for sheet attachment and speed ratings. Ensure the backing pad or sanding block is clean and free of debris before mounting the sheet to avoid uneven contact. Use appropriate respiratory protection when sanding materials that generate fine dust. This sheet is rated for dry use only — do not use with water, cutting fluids, or other wet media.
