67196 - PFERD POLIFAN-CURVE 5-Inch Flap Disc 40 Grit for Fillet Welds

The Ultimate Flap Disc for Tight Corners and Fillet Welds

Every welder knows the frustration of trying to grind a fillet weld with a standard flap disc. You either wear out the edge immediately, or you have to jam the grinder in at an awkward angle, risking damage to the workpiece. The PFERD POLIFAN-CURVE 5-inch Flap Disc changes the game completely. It is built with a unique radial curve that is literally shaped to fit right into the fillet weld. This means you can grind the entire bead evenly without having to fight the grinder. It’s designed to make the toughest part of the cleanup process the easiest.

This 40-grit beast is made for hogging off metal. Whether you are working on mild steel or stainless steel (INOX), the Zirconia abrasive grain cuts fast and stays cool. One of the biggest headaches with aggressive grinding is glazing over or melting the backing pad onto your work. PFERD solved this with a high-quality fiberglass backing that won't melt, smear, or scratch your metal, even when you are leaning into it. You get a clean, consistent cut from the first spark to the last.

Versatility is another huge plus with the Curve disc. Because the flaps wrap around the edge and top, you aren't limited to just the bottom face of the disc. You can flip the grinder over for underhand work or use the sides to blend contours effortlessly. It gives you the control of a smaller tool with the stock removal power of a heavy-duty angle grinder. If you are doing structural repairs, tank fabrication, or any job with a lot of T-joints and corners, this disc will save you time and keep your welds looking professional. Stop struggling with flat discs in round corners and switch to the disc designed for the job.
