3M 7000118368 Abrasive Sheet 40 Grit 2.75x17.5 in

Product Description

The 3M 7000118368 is an aluminum oxide abrasive sheet designed for sanding and material removal tasks in trade and industrial finishing applications. Built on a D-weight paper backing with an open-coat construction, this sheet runs cooler and resists loading during aggressive stock removal. The 40-grit designation makes it suited for coarse-level material removal, shaping, and surface prep before progressing to finer grits. Licensed trades, finishing contractors, and shop professionals install and use this product as part of a structured sanding sequence on wood, metal, fillers, and composite surfaces.

This abrasive sheet measures 2.75 inches x 17.5 inches, a format commonly used with long-board sanders and hand-sanding blocks in both residential remodeling and light commercial finishing work. The open-coat aluminum oxide construction helps extend sheet life by reducing clogging when working with soft woods, spackle, body filler, or primed surfaces. It is sold in box quantities and fits standard sanders that accept this sheet size.

Installation Notes

Abrasive sheets are installed and used by finishing contractors, painters, woodworkers, and general trade professionals.
