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.

Another challenge is the presence of natural fractures and cavities within the limestone. These can lead to instability during drilling, potentially causing borehole collapse or drilling deviation. To address this, engineers use techniques like underreaming or casing to reinforce the hole and maintain stability. Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planningdrilling through limestone.
