The Right DTH Bit for Your Rock Formation
Once compatibility is confirmed, success lies in selecting the optimal bit design for your specific geology. We’ve simplified this complex technical decision into a clear, guided process.
1. Select Your Bit Face by Rock Type
The face design directly impacts performance in different ground conditions.
| Face Design | Visual | Ideal Rock Conditions | Core Advantage |
| Concave | ![]() | Medium-hard to hard, fractured rock formations. | Superior hole straightness; an excellent all-around choice for most applications. |
| Convex | ![]() | Soft to medium-hard, non-abrasive rock (e.g., shale, limestone). | Maximum penetration rate for significantly boosting daily footage. |
| Flat Face | ![]() | Very hard, abrasive, and broken ground (e.g., granite, basalt). | Ultimate durability and wear resistance for the most demanding challenges. |
2. Balance Speed and Lifespan: Choose Your Carbide Button Shape
The shape of the carbide buttons represents a direct trade-off between drilling speed and bit life.
| Carbide Shape | Visual | Best For (Rock Hardness/Abrasiveness) | Best For (Rock Hardness/Abrasiveness) |
| Dome / Round Button | ![]() | Hard to very hard, highly abrasive rock. | Exceptional durability, longest possible service life, and high resistance to breakage. |
| Ballistic Button | ![]() | Soft to medium-hard, non-abrasive rock. | Fastest penetration rate due to its aggressive, penetrating profile. |
| Parabolic / Semi-Ballistic Button | ![]() | Medium-hard, low-abrasion rock. | The perfect balance between drilling speed and longevity; a versatile performer. |
