How to use

Mount the disc on an appropriate 125 mm angle grinder using the M14 thread and ensure the 22.23 mm arbor fits securely. Verify the grinder speed does not exceed 12,250 rpm. Hold the grinder with both hands and apply steady, even pressure while moving across the metal surface. For best results, use smooth, controlled passes and avoid forcing the tool to prevent premature wear of the abrasive cloth.

Recommendations

Use appropriate personal protective equipment (safety goggles, gloves, hearing protection and respiratory protection). Check the disc for damage before use, and replace if torn or overly worn. Allow the disc to cool periodically during prolonged work to extend service life. Store in a dry place in the original packaging.
