Our 3M™ Cubitron™ II Hookit™ Clean Sanding 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.
Now available from grades 80+ through 1000+, these discs are designed for a wide array of substrates and applications,providing flexibility and versatility in use. The discs are effective for a broad range of tasks from stock removal to fine finishing on various substrates, including metals, paint coatings, composites, gelcoat, and different types of wood. The C-weight paper backing offers flexibility and is suitable for sanding applications where edge retention is not the main concern. For best results, pair with 3M Xtract™ Random Orbital Sanders. Sandpaper discs cut better and last longer when dust isn't loading the cutting surface of the abrasives. Our proprietary multi-hole pattern on 3M Xtract™ products removes dust at a higher rate than 5- or 6-hole products. This hole design doesn't even require alignment of holes with the disc pad, making disc changes quick and simple. For maximum dust extraction, use this disc with a 3M Xtract™ Back-up pad and a random orbital sander with vacuum (both sold separately).
