Up to 2 times faster than Bosch C420 sandpaper. Sanding large areas is time-consuming: Many sandpapers quickly clog with dust and lose their abrasiveness, which prolongs the actual sanding process. The EXPERT C470 sandpaper retains its exceptional capabilities through a combination of sharp grains and special technology that prevents clogging. This means you can work faster and longer without compromising on sanding results. To achieve the best possible sanding surface, our production method aligns the grains for aggressive cutting, ensuring their sharpest side is facing up. We then cover them with a strong bond and a coating to prevent clogging. This, along with optimal grain density, ensures maximum speed and minimal clogging. Spend less time sanding or get more done in the same time - with Bosch EXPERT C470 sandpaper. Easy attachment with Velcro.
