Special Line SG-PLUS - POLIFAN SGP-CURVE - POLIFAN SGP CO-CURVE

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.

The POLIFAN® SGP CO-CURVE is designed for demanding grinding, especially for achieving fine surface finishes. The top-sized ceramic grain guarantees cool grinding on poor heat-conducting materials, without thermal damage to workpiece.

    • Abrasive: Ceramic Oxide CO
