Product feature of Rock Drilling Tools
Drill Rod
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 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 .
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.
Products are precision machined from high quality steel, then heat
treated to insure strength and durability.
