3M 7000118247 Sanding Sheet 36 Grit Aluminum Oxide

Product Description

The 3M 7000118247 is an aluminum oxide sanding sheet designed for aggressive material removal in dry sanding applications. Rated at 36 grit, this sheet falls in the very coarse grade range, making it suitable for rapid stock removal, surface leveling, and preparation work on wood, metal, and composite materials. The D-weight paper backing provides a firm, stable base that resists tearing under heavy pressure. Open coat density reduces loading, helping the sheet clear debris and extend usable life during demanding work. This sheet is part of the 3M 346U series, a line built for consistent cut performance in professional and industrial environments.

This sanding sheet is used in hand-block sanding and machine sanding setups where aggressive cutting action is needed at the start of a finishing sequence. Typical applications include rough shaping of wood surfaces, removal of mill scale or rust from metal, and preparation of substrates before moving to finer grits. It is a dry-use sheet only and is not rated for wet or waterproof applications. Woodworkers, metal fabricators, and finishing tradespeople commonly use this sheet in production and maintenance settings.
