ABSTRACT OF THE DISCLOSURE A threaded connection for the stem of raise bore mining drills has substantially extended fatigue life as a result of relieving the radius of the bottom of the thread roots and cold working the relieved radius. The endurance life of the threaded connection is greatly increased by reducing the stress concentration in the thread root and placing the thread root in compression.
