Product Description

Product Description

Introduction:

It is a kind of high air pressure dth drill bit ,our newest design.It is also one of the most advanced DTH drill bit in the world.

Application: 

Using mining industry, energy, metallurgy, geology, coal, water conservancy, chemical industry and road construction.

Our Advantages:

1.WE CAN PROVIDE THE COMPLETE SOLUTION ( DTH drill bit, DTH hammer, DTH Drill Rod, Air Compressor, DTH Drilling rig and added value services) 
2.Lower energy consumption and higher impact frequency.the drilling speed is 15%~30% higher than other series DTH Hammer.
3.Simple structure,reliable parts,long life,easy and cheap maintenance.
4.Lower air and oil consumption.The oil consumption is about 10% lower than the one with foot valve.
5.The check valve can be replaced to the one with bigger ail controlling hole to provide more efficient cuttings discharge.
