    If grinding and finishing are a two tool process for you, you are simply working in the past. Black Hawk Zirconia Flap Discs turn stock removal and finishing into a single, quick and easy process that is bound to save you time and money.

    Black Hawk Zirconia Flap Discs are manufactured using premium Zirconia grain, European cloth and fiberglass backing. 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 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.
