-CURVE is a PFERD innovation designed
to quickly achieve a smooth, consistent surface
finish on fillet welds.
Available in Zirconia for Steel, Ceramic Oxide for
Stainless and A-ALU for non-loading performance
on Alunimum and non-ferrous metals.
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.
Recommendation for Use
The best results are achieved on high-performance
angle grinders.
