How to use

Fit the disc to an X-LOCK-compatible angle grinder following the tool manufacturer's safety instructions. Ensure the grinder is disconnected from power when mounting. Secure the disc on the 22.23 mm arbor using the X-LOCK quick-change system. Operate the grinder at the recommended speed and apply steady, even pressure over the workpiece while keeping the disc angle appropriate for the task.
