DeWalt Metalworking Zirconia Flap Discs

DeWalt Zirconia Flap Discs are made of a series of overlapping cloth-backed sandpaper segments that have been designed to wear away, constantly exposing fresh new abrasive grains. The flap disc removes material quickly and leaves a high quality finish. This ability to aggressively remove material and leave a clean finish in one step is the advantage over fiber resin discs.
