GT60 MF Round Extension Drill Rod

GT60, the drill string components feature an entirely new thread design. Compared with T51 rods, the 40% larger rod cross-section of the GT60 rods provides 65% higher bending stiffness and withstands the Impact-waves from the piston much longer. So much so that both drill-rod and shank adapter life can be doubled. As an extra bonus, the more rigid drill string permits optimum drilling patterns and higher rates of penetration.

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.
