Button bit is renowned for its exceptional wear resistance when drilling on medium-hard to hard abrasive rock formations with compressive strength ranging from 200 Mpa to 260 Mpa. This resilience is attributed to its spherical tungsten carbide inserts which provide added strength and resistance against carbide fractures.
The thread button bit is commonly used in drifting and tunneling applications, thanks to its specialized design that is perfect for medium-hard to hard abrasive rock formations. It is available in various colors, including yellow，gold，green, blue, or as per customer requirements.

| 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. |
