Up to 2 times faster than standard sanding paper - the grinding of large surfaces is time-consuming: Many sanding sheets quickly settle with dust and lose their abrasive properties, which means that the actual grinding process takes more time. By combining sharp grains and special technology that prevents clogging, the Expert C470 sandpaper retains its special capabilities. This means you can work faster and longer without compromising the grinding result. In order to achieve the best possible grinding surface, our aggressive grain alignment production method aligns the grains so that their sharpest side is at the top. Then we cover them with a strong bond and a coating to prevent constipation. This, together with an optimum grain density, ensures maximum speed and minimum clogging. Spend less time grinding or do more work at the same time with the Bosch Expert C470 sandpaper. Simple attachment with Velcro fastener.This text is machine translated.
