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

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.

Our Advantages as below:1. High quality steels materials. Steel is from TIMKEN and Tungsten carbide are YK05, or T6 from Element Six in Germany2. Kingdrilling DTH tools are forged by advanced electron-hydraulic forging hammer.3.Advanced heat-treatment equipment: multipurpose furnace heat treatment.4. Completed moulding (tooling ) departments with many molds available.5.Professional R&D team,completed quality system.6.Strict Quality-Check Systems.
