How to use

Fit the grinding disc to a compatible angle grinder, preferably with X-LOCK mounting if available, and ensure the grinder is unplugged or the battery removed during fitting. Use appropriate rotational speed as specified by the grinder and the disc’s marked maximum RPM. Apply steady pressure, moving the disc across the weld or surface in smooth passes to avoid excessive heat build-up. Replace discs when abrasive performance declines or if damage is visible.

Recommendations

Use appropriate personal protective equipment including safety goggles, gloves, ear protection and a dust mask. Allow metal to cool between passes if excessive heat appears. Match disc diameter and RPM rating to the angle grinder and follow manufacturer safety instructions.
