Up to 2 times faster than standard sandpaper - Sanding large surfaces can be time-consuming: Many sandpapers quickly clog with dust and lose their abrasiveness, making a long process even longer. By combining sharp grains and clogging prevention technology, the Expert C470 sandpaper maintains its exceptional capabilities. This means you can work faster and longer without compromising on the finish. 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 optimal grain density, ensures maximum speed and minimal clogging. Spend less time sanding or get more work done - with the Bosch Expert C470 sandpaper. Easy attachment with Velcro.
