No, this tool is designed for external threads only.

Refer to the markings on the tool and compare with a known good thread. Adjust the tool until it matches the diameter of the thread you are repairing.

Clean the tool after each use, lubricate it regularly, and store it in a clean, dry place.

If the threads are severely damaged, the tool may not be able to restore them. In this case, consider using a thread file or replacing the component.

Check that the tool is correctly adjusted for the thread pitch and diameter. Ensure that the chaser is sharp and that sufficient lubrication is applied.

The damage may be too severe. Consider using a thread file for minor imperfections, or replacing the component if the damage is extensive. Ensure that the tool is being used correctly and is appropriate for the damage.

Ensure the tool is properly aligned with the damaged thread. Apply even pressure and ensure sufficient lubrication. Check for any damage or wear on the chaser.
