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.

At its core, a tunneling tool creates a 'virtual pipe' through which data packets can travel, often masking their true origin or destination. This is particularly useful when dealing with firewalls or network restrictions that might block certain types of traffic. For instance, a common application is the use of SSH (Secure Shell) tunneling to securely access resources on a remote network by encapsulating non-secure protocols within a secure SSH connection.
