Our 3M Cubitron II Hookit paper disc 732U features 3M precision shaped ceramic 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, resulting in a disc that cuts up to 2X as fast and lasts up to 4X as long as conventional abrasives. These discs are ideal for a broad range of applications focused primarily on stock removal, and are effective on a wide variety of substrates, including metals, composites, gelcoat and whitewood. The C-weight paper backing is well suited for sanding applications where edge retention is not a primary requirement. For best results, pair with 3M elite random orbital sanders. We offer a complete line of hook and loop style 3M Hookit discs is available 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 reused again and again for the extent of the abrasive life.
