Kindly Note: We can also design and manufacture the different diameter, holes number, carbide button shape and face shape according to the customers' requirement. Order Guide: Shank Type + Head Diameter + Face Design + Button ShapeHow 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.
