Order Guide: Shank + Head Diameter + Face Design + Button Shape
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.
