POLIFAN Curve Flap Wheels, 4-1/2 in

Tough and aggressive – removes scale and bead from all metals. Multi-purpose – may be used as a conventional flap disc, and also for underhand applications using the top of the disc. Works faster than grinding wheels without the risk of undercutting the work piece. 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.
