Up to 2 times faster than standard sandpaper - Sanding large surfaces can be time-consuming: Many sandpapers clog quickly with dust and lose their abrasiveness, making a long process even longer. The combination of sharp grains and clogging prevention technology allows the Bosch Expert C470 sandpaper to maintain its exceptional performance. This means you can work faster and longer without compromising on the finish. To achieve the best possible sanding surface, the production method aligns the grains aggressively so that their sharpest side is on top. They are then coated with a strong bond and a clogging prevention layer. This, along with optimal grain density, ensures maximum speed and minimal clogging. Spend less time sanding or get more work done - with Bosch Expert C470 sandpaper. Easy attachment with Velcro. Sheet size, width mm: 100, sheet size, length mm: 150, sheet size mm: 100x150, grit: 120.
