3M 7100067789 Scotch-brite Hook-it 8 Inch Finishing Disc

Product Description

The 3M 7100067789 is a Scotch-Brite Hook-It Production Clean and Finish Disc built for fine finishing, scratch blending, and paint prep work on a wide range of surfaces. The non-woven abrasive construction uses aluminum oxide mineral in a three-dimensional structure that delivers consistent cut and finish throughout the life of the disc. Rated to 6000 RPM, it is suited for use with compatible hook-and-loop backup pads on angle grinders and random orbital tools. The 8-inch diameter format is commonly used in metal fabrication shops, body work, and composite finishing environments by machinists, metalworkers, and finishing technicians.

This disc is effective on aluminum, stainless steel, mild steel, plastics, wood, and fiberglass. It is designed for conditioning and surface prep tasks including scuffing primer, blending scratches, and preparing surfaces before paint or coating application. The non-woven structure conforms well to irregular and contoured surfaces, allowing the disc to work into recesses without undercutting or gouging the base material. Minimum order quantity for this item is 20 units, making it appropriate for shop stocking by production finishing operations.
