Description:
Different face style makes DTH bits suitable for various rock conditions.
Flat face: This is an universal design, especially for hard and abrasive rock formation. So typically, flat face with hemi-spherical buttons design is the most popular choice.
Convex face: A classic design for soft to medium hard rock formation which is not so abrasive. This design have very excellent penetration rate but poor in hole deviation if rocks are hard.
Concave face: Medium hard to hard rock formations which is less abrasive and fractured. Especially for deep hole drilling, excellent control over hole deviation.
DGR face: A special design for hard or very hard rock conditions, double gauge row buttons provide very excellent ware-resistance and very longer life time. It is usually used for some bigger diameter DTH bits.
Besides, we are manufacturing the DTH bits with various shanks so they can be compatible with different DTH hammers.

FAQ
1. The Quality of Drill bit?
We have many series of rock bits,quality grades are different,and prices are different.We believe,the proper tools with higher cost-performance isthe most impormant.
2. How to send inquiry?
It is better send us detailed specificaltions of products,it is better attaching some photos for better understanding.If you are not experienced on drilling fields,for example,many customers don't know IADC code,please feel free,jusst tell us the applications like oil/gas/geothermal/HDD/ware/mining,depth of well,average hardness of rocks,then we will advise suggestions and solutions.
