Up to 2 times faster than standard sandpaper - Sanding large areas is time consuming: Many sandpapers quickly become clogged with dust and lose their abrasiveness, making the actual sanding process take more time. By combining sharp grit and special technology that prevents clogging, Expert C470 sandpaper maintains its special abilities. This means you can work faster and longer without compromising on the sanding result. To achieve the best possible sanding surface, our production method for aggressive grain alignment involves orienting the grains so that their sharpest side is on top. We then cover them with a strong bond and coating to prevent clogging. This, along with optimum grain density, ensures maximum speed and minimum clogging. Spend less time sanding or get more work done in the same amount of time with Bosch Expert C470 Sandpaper. Easy attachment with Velcro fastener.
