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.
