Up to 2 times faster than standard sandpaper. Sanding large surfaces is time-consuming: Many sandpapers quickly become clogged with dust and lose their abrasiveness, making a long process even longer. By combining sharp grains and clogging prevention technology, Expert C470 sandpaper retains its exceptional capabilities. This means you can work faster and longer without compromising on the finish. To achieve the best possible sanding surface, the production method for aggressive grit orientation involves orientating the grits so that their sharpest side is on top. They are then covered with a strong bond and a coating to prevent clogging. This, along with optimal grit density, maximises speed and minimises clogging. Spend less time sanding or get more employees to work - with the Bosch Expert C470 sandpaper. Easy attachment with Velcro fastener. Disc diameter: 125 mm, grit: 320.
