Perfect for sanding contours, profiles and carved parts, the Sand-O-Flex wheel is a quick fix for these sanding problems. The abrasive flaps are backed by brushes that help to push the sandpaper into the desired surface shape. The slashed abrasive works great on more severe profiles and contours or for flat surfaces and minor contours. The replacement sandpaper is held conviently in the center core of the wheel so when you need to "freshen" your sandpaper, simply pull it out of the core and cut off the old ends. For use on item MA35000.
