3M 7000118221 Hookit Abrasive Sheet 80 Grit 4.5x30 in

Product Description

The 3M 7000118221 is a Hookit abrasive sheet designed for aggressive material removal in metalworking and woodworking applications. Built on an E-weight heavy paper backing, it uses Cubitron abrasive grain bonded with a resin system engineered for heat resistance during extended use. At 80 grit, it removes stock quickly while leaving a surface ready for finer finishing passes. The sheet measures 4.5 inches wide by 30 inches long, making it compatible with hook-and-loop backup pads and orbital sanders used in professional shop and field settings. HVAC fabricators, metal fab technicians, and woodworking professionals are the primary installers of this product.

This abrasive sheet is suited for flat and low-contour surfaces in both metalworking and woodworking environments. Typical applications include deburring sheet metal, removing weld scale, stripping paint or coatings, and initial surface prep on wood panels. The E-weight paper backing provides rigidity for flat surface work without premature tearing under moderate pressure. It is sold individually and intended for use with compatible Hookit hook-and-loop backing pads and sanders.
