How to choose the suitable head face of the DTH drill bit?- Concave:
Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.- Convex:
Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.- 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.Product Application
It is widely used in all kinds of drilling, such as open-pit mining, underground mining, quarrying, tunneling, benching and engineering construction.
