This pack of 10 Bosch C430 Expert sanding sheets measures 115mm x 280mm with a 40g (very coarse) grit — designed for heavy material removal, rough shaping, and tackling heavily coated or uneven surfaces where fast stock removal is the priority. The electrostatic open-coated surface keeps space between the grits to ensure consistent dust removal and prevent sheet clogging, even when working with demanding materials. The tough abrasive grit is built to resist wear, enabling extended and repeated use, while the fully synthetic resin bonding adds structural durability throughout. With a highly flexible C-/B- paper backing that folds without cracking, these sheets are easy to use with a suitable backing pad and clip on securely to orbital sanders.
