Wide range of products, matching different working conditions
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.
1. Our threaded drill pipe is made of high-strength alloy steel
imported from Sweden and Shanghai Baosteel.
2. All traces and threads are shaped by high precision CNC machine
tools.
3.MF rod adopts mature friction welding technology to improve the
service life of thread.
4. Overall carburizing increases the carbon content of the outer
part of the drill pipe and hardens the outer steel body.
5, solid thread and the inner wall of the drill bit perfect fit,
high precision, high efficiency to complete the complex rock and
terrain rough drilling in various roadway driving, underground
mining and open drilling tasks.
Extension drill rod is used in drifting, tunneling, long-hole
drilling, bench and production drilling.
Our drilling tools are designed to deliver high production footage
at the lowest possible cost.
