Hydraulic Rock Drilling Tools Reaming Bits DTH Hole Opener
Introduction
Big hole high air pressure DTH hammer using in water well, oil, gas and construction drilling
Eccentric overburden drilling Equipment
DTH hammer drill bit manufacturer DTH drill bit is made of the highest quality aircraft alloy steel. The most commonly used methods for expanding the size of pilot holes are blast hole drilling, quarrying, down-the-hole drilling, water well drilling, oil drilling, construction, and foundation drilling.
Our Advantages as below:
High-quality steel.
DTH tools are forged by advanced electronic hydraulic forging hammers.
DTH hole openers are used to expand the size of pilot holes that are commonly used in industrial applications.
The ability to use is not as powerful as the equipment required to drill large diameter holes.
All hole openers are made of the highest quality aircraft alloy steel.
Straight holes are produced by smaller guide holes.
Better removal of cutting materials.
Advanced heat treatment equipment: multi-purpose furnace heat treatment.
Complete molding (mold) department, providing many available molds.
Professional R&D team and perfect quality system.
Strict quality inspection system.

How to choose the suitable head face of the DTH drill bit?
1. Concave:
Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.
2. Convex:
Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.
3. Flat:
Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole.
