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

Precision Engineering for Fillet Weld Applications

The PFERD POLIFAN-CURVE Flap Disc represents a significant leap in abrasive technology, specifically engineered to address the challenges of working on fillet welds. Unlike conventional flap discs that primarily utilize the face or edge, the POLIFAN-CURVE features a patented radial configuration. This unique design allows the abrasive flaps to wrap around the periphery of the disc, creating a geometry that perfectly matches the contour of fillet welds. For industrial MRO and fabrication environments, this translates to precise grinding of weld geometry without the risk of gouging or undercutting the base material.

Part of PFERD's Special Line SGP, this tool is designed for tasks requiring high performance and ultimate economic efficiency. The abrasive composition is a sophisticated blend of Zirconia and Aluminum Oxide grains, optimized to deliver aggressive stock removal rates while maintaining a long service life. This is particularly critical in high-volume production settings where downtime for disc changes can impact overall throughput. The 40-grit specification ensures rapid material removal, making it ideal for heavy-duty grinding on both Steel and Stainless Steel (INOX).

The structural integrity of the disc is supported by a robust fiberglass backing. This material choice is deliberate; unlike plastic backings that may melt under the high heat generated during aggressive grinding, fiberglass remains stable. This prevents the backing from smearing onto the workpiece or causing scratches, ensuring a clean finish that requires less rework. The radial shape also offers unmatched versatility, allowing operators to perform conventional surface grinding as well as complex underhand applications using the top surface of the disc. The PFERD POLIFAN-CURVE is not just a consumable; it is a specialized solution for achieving superior structural integrity and finish in complex weldments.
