Button Bit

Threaded button bit, a kind of rock drill bits for hammer drill  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. It uses different forms of threads to cooperate with the drill rod to perform drilling operations.

Threaded Button Bit
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 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
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.

Button Bits Rock Drilling Advantages

High-quality raw material
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.

Advanced button fixation technology  
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.

Advanced thread manufacturing process
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.

Excellent rock drilling bits design
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.

Strict quality control
All button drill bits for rock drilling have implemented strict quality control to ensure that each button drill bit is of high quality.

Button Bits Selection

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

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 Button Bit

Drop Center

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.

Convex Face Button Bit

Convex

Convex Face button bits are designed for fast penetration rates in softer rock.
