The hardness of limestone can vary greatly, from relatively soft to extremely hard, depending on factors such as its mineral content and degree of compaction. Soft limestones can be easily drilled using standard drilling equipment, but harder varieties often necessitate more robust machinery and specialized bits. Carbide-tipped drill bits, for instance, are commonly employed due to their durability and ability to withstand the abrasive nature of limestone.

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.
