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 with clogging prevention technology, the Expert C470 sandpaper maintains its exceptional capabilities. This means you can work faster and longer without compromising on finish quality. To achieve the best possible sanding surface, our production method aligns the grains aggressively so that their sharpest side is on top. We then cover them with a strong bond and a clogging prevention coating. This, along with optimal grain density, ensures maximum speed and minimal clogging. Spend less time sanding or get more done - with Bosch Expert C470 sandpaper. Easy attachment with Velcro. Disc diameter: 93 mm, grit: 320.
