Button bits for rock drilling, a kind of top hammer drill bit and rock drill bit, is mainly used with hydraulic drill rods (pneumatic drill rods) and hydraulic rock drills (or pneumatic rock drills) in top hammer drilling. Button bits rock drilling use different forms of threads to cooperate with the drill rod to perform drilling operations.

Working with hydraulic drill rig, Threaded Drilling Tools are widely used in tunneling, mining and construction field because of high drilling efficiency, safety and environmental protection.
The thread type includes R25,R28,R32,SR35,R38,T45,T51, ST58, GT60, ST68 and so on.
R25, R28, R32, R38
Used in drifting and tunneling.
T38, T45, T51, ST58, ST68
Used in benching and long hole drilling.
The buttons have different shapes,such as spherical,ballisticand conical.
Spherical Button Characteristics:
1. Universal button
2. Good wear resistance
3. Best suited for hard ground
4. 27000-48000PSI(180 to 320Mpa)
5. Suited for abrasive to very abrasive drilling conditions
Ballistic Button Characteristics:
1. Fast Penetration
2. Best suited for soft rock
3. 10000-20000PSI(70 to 140Mpa)
4. Suited for non-abrasive drilling conditions
The face shapes include flat shape,drop-center shapes and engrave shapes,the body shapes have normal and retrac shapes.

| 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. |
