3M 7000118258 Cloth Sheet 211K 400 Grit 9x11 in

Product Description

The 3M 7000118258 is a J-weight cloth abrasive sheet designed for precision sanding and finishing applications across metal, wood, and composite surfaces. Sold under the 211K product line, this sheet measures 9 inches x 11 inches and carries a 400-grit rating, placing it in the fine finishing range. The J-weight cloth backing provides flexibility for contour sanding while maintaining enough body for flat-surface work. Each case contains 250 sheets, packaged in inners of 50, making it practical for shops and field crews that go through abrasives at volume. Trade professionals such as HVAC fabricators, sheet metal workers, and finishing contractors rely on consistent grit rating and backing weight for repeatable surface prep results.

This abrasive sheet is suited for light material removal, surface blending, and pre-finish preparation on ferrous and non-ferrous metals as well as finished wood surfaces. The fine 400-grit cut makes it appropriate for final prep stages before coating, painting, or polishing. It is commonly used in light industrial settings, HVAC duct fabrication shops, and general trade environments where surface quality directly affects the adhesion or appearance of a finished coating. The full-case quantity of 250 sheets supports ongoing production use without frequent reorder.
