Introduction
Big hole high air pressure DTH hammer using in water well, oil, gas and construction drilling
Eccentric overburden drilling Equipment
DTH hammer bit manufacturer DTH hole opener bits are manufactured from the highest quality aircraft alloy steel. Which are used to enlarge the size of a pilot hole most commonly for Blast hole drilling, Quarrying, DTH Drilling, Water Well Drilling, Oil Drilling, Construction, Foundation Drilling.
Our Advantages as below:
High quality steels materials.
DTH tools are forged by advanced electron-hydraulic forging hammer.
DTH hole openers are used to enlarge the size of a pilot hole most commonly apply to industrial applications.
All Hole Openers are manufactured from the highest quality aircraft alloy steel.
Straigher holes result from the smaller pilot hole.
Better clearing of cut material.

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.
