ABRASIVES - Flap Discs 

Fillet Grinding Disc
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.
Works faster than grinding wheels without the risk of under cutting the work piece.
Precise grinding out of fillet welds provides a superior 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.
Multi-purpose – may be used as a conventional flap disc, and also for underhand applications using the top of the disc.

Application: Fillet weld grinding, chamfering, deburring
Recommendation for Use: The best results are achieved on high-performance angle grinders.
