Threaded button bits for rock drilling, a kind of top hammer 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.
Litian, a reliable button bits factory, offers high-quality top hammer button rock drill bits for sale at competitive prices. We have the most of threaded button bits that you need, such as R32 drill button bit, t38 drill bits, t45 bits, T51 bits, etc. Check more about our hard rock drill bits and soft rock drill bits in the following!
In top hammer threaded drilling tools, standard threaded button bit is the most widely used drill bit, which can be applied to all rock conditions. Our standard button bits are R25 button bit, R32 button bit...
Retrac button bits are mainly used in loose rock mass with relatively broken rock. The retrac skirt design can assist in retrieving the drill tool, reduce the phenomenon of bit stuck and buried.
Reaming bit is a hole opener that drills a pilot hole to a certain depth and then reams the hole to a larger diameter. It is mainly used for center hole reaming in long hole drilling.

We offer different threaded Button Bit Types including standard button bit, retrac button bit, pilot reamer bit, spherical button drill bit, ballistic button bit, flat face drill bit, drop center drill bit etc. What's more, custom design of hard rock drilling bits is supported.
Our button rock drill bits are made of high-quality steel and cemented carbide as raw materials. After a special heat treatment process, the drilling rig drill bit has a long service life and can minimize the loss of impact energy during transmission.
The drilling rig drill bit adopts advanced button fixation technology. The fixation force is uniform and it is not easy to lose buttons. At the same time, it can ensure the verticality of the drilling hole, so that the impact energy can be concentrated on the rock.
Our drill button bits are with advanced thread manufacturing technology. Threads manufactured with precise tolerances enable the drill bit and the drill rod to be connected more tightly, and can transmit impact energy more effectively, while greatly reducing the risk of dents and fractures at the thread end, and improving overall production efficiency. In actual use, many of our thread button bits, such as R32 button bit, T38 drill bits, T45 drill bits, T51 bits are all have good performance.
Litian is one of the experienced drill bit manufacturers in China and we have many face designs of drill button bits suitable for different rock formations, which can meet the drilling requirements of different hardness rocks, improve drilling efficiency and reduce costs.
All button drill bits for rock drilling have implemented strict quality control to ensure that each button drill bit is of high quality.
For different rock formations and drilling requirements, button rock drill bits need to be equipped with different types of bit faces, skirts and carbides.
Bit Face Selection
| Face Design | Application |
Flat Face | 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. |
Drop Center | Drop center button drill bits are mainly suitable for the rock with low hardness, low abrasiveness, and less consolidation. The bits can drill straighter holes. |
Convex | Convex Face button bits are designed for fast penetration rates in softer rock. |
Button shapes | Application | |||
Rock Hardness | Penetration Velocity | Carbide Service Life | Vibration | |
Spherical Buttons | Hard ■■■ | Slower ■□□ | longer service life less prone to breaking ■■■ | More ■■■ |
Ballistic Buttons | medium Soft ■■□ | Faster ■■□ | shorter service life more prone to breaking ■■□ | Less ■□□ |
Conical Buttons | Soft ■□□ | Faster ■■■ | shorter service life more prone to breaking ■□□ | Less ■□□ |
Skirt Selection
Skirts | Application |
Standard Skirt | Standard skirt button drill bits are suitable for all rock conditions. |
Retrac Skirt | Retrac button drill bits are mainly used for unconsolidated rock mass with poor integrity. The skirt is designed to improve the straightness of the drilling hole and assist in the retrieval of drill rock tools. |
Litian is a professional manufacturer focused on the production of rock drilling tools and excavation tools.
