Up to 2 times faster than standard abrasive paper: sanding large surfaces takes a lot of time: many abrasive sheets quickly clog with dust and lose their abrasive properties, which means the actual sanding process takes longer. By combining sharp grains and a special technology that prevents clogging, the Expert C470 sandpaper retains its special capabilities. This means you can work faster and longer without compromising the sanding result. To achieve the best possible sanding surface, our aggressive grain alignment manufacturing method aligns the grains so that their sharpest side is 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 do more work at once with Bosch Expert C470 sandpaper. Easy attachment with Velcro closure.
