What Sets Our Discs Apart?

  • All-in-One Solution: Designed for multiple applications, saving you money and decluttering your toolbox. No more need to store multiple tools like grinding wheels and fiber sanding discs
  • Fast cutting: Zirconia is a sharper and harder abrasive than aluminum oxide, making it the best flapper disc for quick cutting and faster material removal
  • Grind Longer: Zirc is long-lasting and self-sharpening. When worn, flaps break off, revealing fresh abrasives for consistent performance. BHA’S high-quality backing plate distributes force evenly, preventing the disc from tearing.
  • Noise Reduction: Low vibration backing plate ensures quieter operation.
  • Smooth Operation: Reinforced backing distributes force evenly across the disc, resulting in consistent grinding results. This means that you can get the same smooth finish every time.
  • Heat Dissipation: Heat-resistant zirconia, increased airflow between flaps, and the T27 design generates less heat when grinding. This makes the discs last longer and protects your surface from discoloration, burning, or warping.
  • Less Clogging: Premium zirconia abrasive grain in our flap discs are self-sharpening and heat-resistant, preventing your disc from clogging.
  • Trusted Brand: Black Hawk Abrasives is trusted by professionals for quality and reliability.
