Product Introduction
Litian provides top hammer drill rod for every application, such as underground mining and tunneling, surface mining and quarries, road and construction.
The threaded drill rods in the top hammer rock drilling tools include extension rods and MF drill rods. The drill bit, drill rod, connecting sleeve and drill tail are connected by the threads to form a rock drilling tool group. Our thread has the characteristics of tight connection, good energy transmission effect, strong wear resistance and easy disassembly. At present, there are two commonly used thread forms: rope thread or trapezoidal thread.
