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

Different Types Of Litian Button Bits

Threaded Button Bit

In top hammer rock drill bits, threaded drill bits, standard threaded button drill bit, rig drill bit is the most widely used rock drill bit, which can be applied to all rock conditions. Our button bits are R25 button bit, and so on.

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 Bit Product Specification

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

Application

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 types of drilling rig bit 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 bits are designed for fast penetration rates in softer rock.

Skirt Selection

Skirts

Application

Standard Skirt Button Bit

Standard Skirt

Standard skirt drill bits are suitable for all rock conditions.

Retrac Skirt Button Bit

Retrac Skirt

Retrac drilling rods and 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.
