67192 - PFERD POLIFAN-CURVE 4-1/2 Inch Flap Disc, 40 Grit Zirconia, 7/8 Arbor

Maximize Productivity with the PFERD 67192 Curve Flap Disc

Grinding fillet welds has traditionally been a challenge for welders and fabricators, often resulting in wasted abrasive discs and uneven finishes. The PFERD 67192 POLIFAN-CURVE Flap Disc changes the game with its innovative radial design. Standard flap discs are flat or slightly conical, meaning only a small portion of the abrasive touches the weld when grinding a fillet. This leads to premature wear on the edge of the disc while the center remains unused. The PFERD Curve disc solves this by arranging the flaps in a radial shape that contours perfectly to the weld seam. This allows you to utilize the entire abrasive surface, drastically increasing the life of the disc and the speed of your work.

This 4-1/2" x 7/8" disc is equipped with a coarse 40 Grit Zirconia abrasive, making it a powerhouse for removing heavy weld beads on both Steel and Stainless Steel (INOX). The Zirconia grain is self-sharpening and tough, designed to withstand the high pressures of angle grinding without glazing over. One of the standout features of the POLIFAN-CURVE is its versatility. Not only does it excel at fillet welds, but its unique shape also allows for "underhand" applications—using the top side of the disc to reach difficult spots that a standard grinder angle can't access. This multi-purpose capability means you can keep one disc on your grinder for a wider variety of tasks, saving time on tool changes.

The construction of the PFERD 67192 is built for the industrial environment. It features a robust fiberglass backing that provides stability during aggressive grinding but will not melt or leave residue on your metal, ensuring a clean surface ready for painting or finishing. The Medium Radius profile is specifically sized to match the most common weld bead shapes, allowing for smooth blending without digging into the base metal. If you are looking to improve your shop's efficiency and reduce abrasive costs, the PFERD POLIFAN-CURVE is the superior choice for fillet weld processing.

Why Choose the PFERD Curve Disc?

• Longer Life: Uses more of the abrasive cloth than standard discs.
• Better Finish: Conforms to the weld for smooth blending.
• Versatility: Grinds on the edge, face, and top.
• Performance: High stock removal on Steel and Stainless.
