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.
POLIFAN® ZIRKON-CURVE is produced with a premium Zirconia material that provides a combination of long service life and high stock removal rates in demanding applications.
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.
Abrasive:Zirconia Alumina Z
Arbore Hole: 7/8 A.H.
Diameter Options: 4-1/2", 5", 6", 7"
Available in two thicknesses:
Mediumfor fillet weld widths > 3/16”(5 mm)
Largefor fillet weld widths > 5/16” (8 mm)
Contamination Free - Rated for working with stainless steel, guaranteed to have no contaminating fillers.
The best results are achieved on high-performance angle grinders. Economy angle grinders do not have enough power to operate these discs and will result in the abrasive material getting clogged faster.
