2.All the trails and threads are formed by high precision CNC machines.

3.For MF rod,we use mature friction welding technology to increase the using life of thread.

4.Holistic carburization increases the carbon content in the outer layer of drill rod, and hardened outer steel body.

5.The solid thread can fit perfectly with the inner wall of the drill bits,and complete various roadway tunneling, underground mining and open pit drilling task in complex rock and terrain rough drilling with high precision and high efficiency .

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.
