Flex Edge Holders/Ext
The Flex Edge discs attach to the Flex Edge Holder in the same manner as the regular Power Lock discs, but are designed so the sanding disc overhangs the holder. The holder has a 1/4" diameter shank. By having approx. 1/4" overhang around the holder, the Flex Edge disc is not as aggressive as the regular Power Lock discs and is less likely to "dig" into the work piece.
