Product Description
Thread drill extension rod made of coal mining alloy high hardness
1.Our thread drill rods are made of high-intensity alloy steel imported from Sweden and shanghai baogang. 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 .
