3M 211K 80-Grit 3-2/3x9in Aluminum Oxide Abrasive Cloth Sheet PK75

This is a new factory pack of 75 sheets of 3M 211K Utility Abrasive Cloth, product number 7010532934, in 80-grit coarse grade measuring 3-2/3 in x 9 in. The 211K designation identifies an aluminum oxide abrasive mineral on a J-weight (lightweight, flexible) cotton cloth backing — confirmed by the "211K J" marking visible on the back of each sheet — making these sheets conformable for hand sanding contoured surfaces as well as flat-stock work. The resin-over-resin bond system provides durability and resistance to heat buildup, and the open-coat construction reduces loading when working on wood, metal, composites, and plastic. At 80-grit these sheets are suited for aggressive stock removal, weld blending, rust and scale removal, and surface preparation prior to finer finishing steps. The 3-2/3 in x 9 in sheet size is a standard 1/3-sheet format compatible with 1/3-sheet orbital finishing sanders as well as hand sanding blocks.
