3M Cubitron II Hookit Clean Sanding Film Disc 775L, 3 in x NH, 220+, D/F, Die 300DS, 50 discs per inner, 250 per case

3M Xtract Cubitron II Disc 775L features a 3M proprietary multi-hole pattern for improved dust extraction in finishing applications. Part of the 3M Xtract Series, designed for optimal dust removal. An innovative multi-hole pattern extracts dust better than 5- or 6-hole products — increasing cut and dramatically increasing disc life. The design does not need to align with the disc pad holes, making switching the discs fast, easy and convenient. Featuring 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, resulting in a disc that cuts up to 2x as fast as conventional abrasives. The film backing delivers outstanding tear resistance, flexibility and a consistent, uniform finish on a variety of substrates.
