Litian Rock Button Bits

Button Bit Product Advantages

High-quality raw material

Our button bits are made of high-quality steel and cemented carbide as raw materials. After a special heat treatment process, the bits have a long service life and can minimize the loss of impact energy during transmission.

Advanced button fixation technology

Our button bits adopt 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.

Excellent product design

We have many face designs 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 drill bits have implemented strict quality control to ensure that each drill bit is of high quality.

Button Bits Selection

For different rock formations and drilling requirements, button bits need to be equipped with different types of bit faces, skirts and carbides.

Bit Face Selection

Face Design



Flat Face

Flat face 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 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 Face bits are designed for fast penetration rates in softer rock.

Carbide Button Selection

Skirt Selection



Standard Skirt Button Bit

Standard Skirt

Standard skirt drill bits are suitable for all rock conditions.

Retrac Skirt Button Bit

Retrac Skirt

Retrac 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 tools.
