Recommendation:
Make sure to lubricate the threads with grease to prolong the life
of the rods and to prevent wear and galling. Special thread
lubricant is the best.
Check the threads on the drill rods regularly. If the threads are
damaged they can damage other rods they are connected to.
If the threading on one rod should get damaged during making of
joint, both rods should be replaced.
