Up to 2 times faster than a Bosch C420 sandpaper. Sanding large surfaces is time-consuming: Many sandpapers quickly clog with dust and lose their abrasiveness, which prolongs the actual sanding process. Thanks to the combination of sharp grains and special technology that prevents clogging, the EXPERT C470 sandpaper maintains its exceptional capabilities. 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 aggressively so that their sharpest side is facing up. We then cover them with a strong bond and a coating to prevent clogging. This, along with an optimal grain density, ensures maximum speed and minimal clogging. Spend less time sanding or get more work done in the same time - with Bosch EXPERT C470 sandpaper. Easy attachment with Velcro.
