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 bithas 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.
