Application Information
- 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.
