Good Value with the Dewalt Crimped Cup attachment

Good Value with the Dewalt Crimped Cup attachment
Good quality lose crimped cup brush from DEWALT. I prefer the Cable Twist Wire versus this Crimped Cup (this item) after testing out both types. I think I will find a use for polishing or lighter work with this attachment, but for now it gets 4 stars. Price versus quality, this Dealt is great value. If you are looking for this type of crimped cup, I recommend this item.
