In addition to breaking through rocks, tunnel bench drilling bits also play a role in stabilizing tunnel walls. As tunnels are excavated, the surrounding soil can become loose and unstable, posing a danger to workers and the structural integrity of the tunnel. Tunnel bench drilling bits are used to create holes for support structures such as bolts and mesh, which help to secure the tunnel walls and prevent collapses. By stabilizing the tunnel walls, these drilling bits ensure the safety of workers and the success of the tunneling project.

Corrosion is a universal concern, causing significant economic losses and structural degradation in various sectors. Traditional materials like steel and concrete are highly susceptible to chemical attack, leading to weakening and eventual failure. However, FRP's unique properties make it a game-changer in combating this issue. The non-metallic nature of FRP ensures that it is not subject to electrochemical reactions, which are the root cause of corrosion in metals. Moreover, its chemical inertness allows it to withstand exposure to harsh environments, acidic or alkaline substances, and extreme temperatures without degrading.

Their operation is straightforward as well. They are commonly used with a drill press for accuracy and stability, but can also be employed with a hand drill, albeit with less precision. The central point guides the bit while the flat edges cut away the material. However, due to their size and design, they are not suitable for drilling into harder materials like metal or masonry However, due to their size and design, they are not suitable for drilling into harder materials like metal or masonry However, due to their size and design, they are not suitable for drilling into harder materials like metal or masonry However, due to their size and design, they are not suitable for drilling into harder materials like metal or masonryflat drill bit.
