DIFFERENT FACES STYLES:
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
