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 lengthy 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, the production method aligns the grains aggressively, ensuring their sharpest side is on top. They are then coated with a strong bond and a clogging prevention layer. Together with an optimal grain density, this provides maximum speed and minimal clogging. Spend less time sanding or get more done - with Bosch Expert C470 sandpaper. Easy attachment with hook-and-loop. Sheet dimensions: width 115 mm, length 107 mm, grit: 120.
