• 3/16" Fillet weld radius • POLIFAN®-Curve is a PFERD innovation designed to quickly achieve a smooth, consistent surface finish on fillet welds. The unique radial construction shape (PFR) offers a superior solution for this common task • Tough and aggressive – removes scale and bead from all metals: steel, stainless steel (INOX), aluminum and alloys • Works faster than grinding wheels without the risk of undercutting the workpiece • Precise grinding out of fillet welds provides a superior surface finish • Smooth finish allows easy visual inspection for defects, such as porosity and inclusions • Ideal for repair applications to remove defects without damage to adjacent areas. Leaves ample room for new weld bead • Excellent tool life, including the radius edge of the disc • Multi-purpose – may be used as a conventional flap disc, and also for underhand applications using the top of the disc • Ideal for: Steel • Suitable for: Stainless Steel (INOX) • Application: Fillet weld grinding, chamfering, deburring Recommendation for use: The best results are achieved on high-performance angle grinders
