The 3M Hookit Cloth Disc 726A features ceramic 3M Precision-Shaped Grain, a revolutionary advancement in abrasive technology. The triangular shaped ceramic mineral is designed to slice through the substrate, rather than gouging or “plowing” like conventional abrasives. The J-weight cloth backing balances durability with flexibility for a wide range of substrates.These discs are ideal for a broad range of applications focused primarily on stock removal, and are particularly effective in tough sanding applications. The cloth backing offers additional durability and edge retention. For best results, pair with 3M Elite Random Orbital Sanders. We offer a complete line of hook-and-loop style 3M Hookit discs for work spaces where adhesive backed discs may become contaminated by dust or dirt. They are often used in applications where a 3M Stikit disc may be too aggressive, as Hookit discs tend to leave finer finishes than adhesive backed discs. Hookit sanding discs conveniently attach to a hook-and-loop backup disc pad (sold separately), can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.
