Up to 2 times faster than standard sandpaper - Sanding large surfaces is time-consuming: Many sandpapers quickly clog with dust and lose their abrasiveness, making a long process even longer. By combining sharp grit and clog prevention technology, Expert C470 sandpaper maintains its exceptional capabilities. This means you can work faster and longer without compromising on finish. To achieve the best possible sanding surface, our production method for aggressive grit alignment aligns the grits so that their sharpest side is on top. We then cover them with a strong bond and a coating to prevent clogging. This, together with optimum grain density, ensures maximum speed and minimum clogging. Spend less time sanding or get more work done - with Bosch Expert C470 sandpaper. Easy attachment with Velcro fastener. Disc diameter mm: 125, grit: 400
