| Face Design | Application |
|
| Flat face button drill bits are suitable for all rock conditions, especially for the rock with higher hardness and higher abrasiveness. Such as granite and basalt |
| Convex Face button bits are designed for fast penetration rates in softer rock. |
|
| Drop center button drill bits are mainly suitable for the rock with low hardness, low abrasiveness, and good integrity. The bits can drill straighter holes. |
|
| Normal Skirt For drilling in very hard and abrasive rock formations. |
|
| Retract Skirt For drilling in loose,broken or fissured rock where it is difficult to retract the drill string due to the hole collapse. |
| Button Shape | |
 | R：Round Utility carbide shape. Stong configuration against carbide fracture. |
 | B:Ballistic Higher penetrating carbide shape than Semi ballistic shape. Recommended for soft rock. |
| BB：Semi Ballistic Combined wear resistance and high penetration rate. Recommended for medium-hard rock with moderate abrasitivity. |
 | SA:Spike Highest penetrating carbide shape. Weak configuration against carbide fracture. Recommended for soft to medium-hard work. |
