The drilling process itself involves a technique known as 'circulation.' A drilling fluid, commonly referred to as 'mud,' is continuously pumped down the drill string, through the bit, and back up the annulus between the drill string and the walls of the hole. This fluid serves multiple purposes it cools and lubricates the bit, carries cuttings to the surface, stabilizes the borehole, and provides hydrostatic pressure to prevent underground fluids from entering.

One of the primary functions of a tunnel bench drilling bit is to break through rock formations. Rocks are often encountered while digging tunnels and can pose a significant challenge to construction workers. Tunnel bench drilling bits are equipped with sturdy and durable materials that enable them to crush through rocks with ease. The design of these bits allows them to create boreholes of various sizes, making them versatile tools for tunneling projects.

The core drill bit extension rod is an elongated accessory designed to connect additional lengths to a core drill bit system. This seemingly simple tool dramatically expands the capabilities of drilling rigs by allowing operators to reach greater depths without compromising on the quality of the borehole. By utilizing high-grade materials and precision engineering, these extension rods ensure seamless integration with the drill bits, creating a unified column that can penetrate through various strata with minimal deviation.
