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. The Expert C470 sandpaper retains its exceptional capabilities through a combination of sharp grains and clogging prevention technology. 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 for aggressive cutting, positioning their sharpest side on top. 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 - with the Bosch Expert C470 sandpaper. Easy attachment with Velcro. Disc diameter: 150 mm, grit: 40.
