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 widely used in metallurgical, coal, chemical, building materials are not busy mines and water conservancy, hydropower, highway and railway defense construction projects, etc.
