        • Fillet weld grinding, chamfering, deburring, contour grinding
        • 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.

          WHAT ELSE?
          • 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.
