4-1/2" x 7/8" Ceramic Angle Grinder Flapper Discs by Black Hawk are great for sanding, blending, grinding, deburring and finishing and come in 36 grit, 40 grit, 60 grit and 80 grit. Made with red premium ceramic abrasive grains on high strength flaps, each disc is crafted for performance.
The classic, high quality flap discs that Black Hawk are known for are now available with the newest innovation in abrasive grain technology: Ceramic Grains. 4.5” Black Hawk Ceramic Flap Discs are designed with ceramic grains resin bonded to high strength polyester flaps which are adhered to a fiberglass backing plate. These ceramic grains are self-sharpening while in use, providing the most consistent cut and rapid stock removal. Moreover, these ceramic flap discs remain cooler than zirconia flap disc alternatives making them the ideal choice for any heat sensitive materials. These Ceramic flapper discs are particularly effective for use on stainless steel, carbon steel allots, and other metals, boasting a 50% longer life than zirconia flap discs working on the same materials. Finally, Ceramic Flap Discs require less pressure to achieve significant stock removal which further extends the life of these flap discs. So if you are looking for a sharp and consistent cut, long-life, and reduced disc changing the Black Hawk Ceramic Flap Discs are the perfect flap discs for you.

I have been in the metal fabrication business for over forty years. I have used many types and brands of abrasives and metal cutting discs. I use the Black Hawk Ceramic flap discs to grind and finish stainless steel which is a good test for any abrasive. This product performs well and is a very good value for your investment when purchasing shop supplies. I must admit that there is another brand that I have been using for many years and I would consider the best in its field but the cost each is double that of the Black Hawk product. I have purchased this product several times now and will continue to use them in my shop.

I don't use these because they don't usually last very long, but these work great and last. Scotty on Jul 26th 2017
