3M Xtract™ Cubitron™ II Cloth Disc 900DZ 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. The 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 J-weight cloth backing delivers outstanding tear resistance, durability and a consistent, uniform finish on a variety of substrates.
