We can design and manufacture the different diameter,holes number,carbide button shape and face shape according to the customers' requirement.
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.

1.  Convex: 

Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.

1.  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 suitable for drilling water wells , geothermal wells , short micro piles ,medium mini-type grouting hole of building , dam and harbour project.
