Round rods are generally lighter than
hexagonal rods and are normally used in extension drilling applications. With the longer steel tending to be larger in diameter, conventional extension steel is characterized by a duplicate thread on each end of the
Heat treatments of Carburization, High Frequency Induction are used to strengthen high speed and powerful percussive drill string components to maximize their performance and reliability. M/F steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.
