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.

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.
