    Are you looking for a way to speed up your jobs without sacraficing quality? Black Hawk Flap Discs both grind and finish in one step without breaking to change abrasives or tools.

    Black Hawk Zirconia Flap Discs consist of sanding strips adhered to a strong fiberglass backing plate in an overlapping circular pattern. Each sanding strip is made using premium Zirconia grain and European cloth. These discs are built for precision, durability and ease of use. Flap Discs are an essential tool for right angle metal grinding applications, and can be used in place of both grinding wheels and resin fiber discs. Zirconia is a long-life premium abrasive that works well on stainless steel, hard steel, titanium and various others. A Zirconia Flap Disc continually produces new sharp points, creating faster cutting and a longer lifespan than aluminum oxide varieties.

    3. double use for the money

      Bought a 10pk to give them a try and so far they have performed better then flap disks costing 3x as much. primarily use them for dros clean up and finishing of some lighter gauge metal. so far I'm using about 1 disk per 4x8 sheet of cut material. I'm happy with that. on Jun 27th 2018

    4. Best flapper discs I've seen for the price

      for under 2 dollars a disc these are the best flappers I've ever used on Jun 8th 2018
