The drill rod adopts a T-shaped thread, which is more favorable for loosening and unloading of the joint portion, and has a larger pitch and a thread side angle than the R-shaped thread. The threaded portion has excellent wear resistance and high connection performance, and is matched with high power and high rotation. Torque rock drill.
T-threaded connections are ideal for use with multiple drill rods. They are specially developed for high-performance drills with large diameter bores. The drill rods are more rigid and help prevent bore deflection. Compared with standard threads, taper trapezoidal threads use 23%-30% more material than normal R-type threads, and have better wear resistance and strength. With the fast female threaded interface, the connection speed is fast, easy to disassemble and install, and its service life is longer than that of the separate connection, the connection is more tight, and the drilling is more excellent.
