The Forney 71931 is a Type 29 flap disc designed for fast grinding and finishing work on right angle grinders. Its blue zirconia abrasive construction makes it ideal for both rough material removal and fine finishing tasks. The multiple layers of zirconia cloth flaps continuously expose new, extra-sharp grinding points, delivering consistent cutting performance and significantly extending the disc’s working life compared to standard sanding discs.
This 4.5-inch disc offers excellent flexibility and control, making it well-suited for detailed work in tight spaces. The reinforced fiberglass backing plate provides durability and stability, while individual balance testing ensures vibration-free grinding and finishing. The disc is straightforward to install on any compatible right angle grinder and works reliably at high speeds up to 13,500 RPM.
