PFERD POLIFAN-CURVE 5-Inch Flap Disc 40 Grit Zirconia Large Radius

Grind Corners and Fillets Faster

Stop struggling to reach into tight corners with standard flat discs. The PFERD POLIFAN®-CURVE 5-inch flap disc is a game-changer for welders working on structural steel, tank fabrication, and general metalwork involving fillet welds. Its patented curved design wraps around the edge of the backing plate, allowing you to grind deep into the throat of the weld with the radius of the disc.

This 40-grit Zirconia powerhouse eats through metal quickly, making it ideal for heavy stock removal and weld blending. The "Large" profile is designed for wider fillet welds (over 5/16 inch), providing a smooth, consistent finish without gouging the base metal. Because the flaps are arranged radially, you get 100% utilization of the abrasive material, meaning fewer disc changes and more arc time. Whether you are working on mild steel or stainless, the POLIFAN-CURVE helps you achieve a professional finish in record time.

Why Choose POLIFAN-CURVE?

• Speed: Removes weld metal faster than traditional grinding wheels in corners.
• Finish: Leaves a smooth finish that often requires no secondary blending.
• Longevity: The unique shape prevents premature edge wear, lasting longer than standard flap discs.
• Comfort: Runs smoother with less vibration than hard grinding rocks.
