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.

  • A 34mm drill bit, as the name suggests, refers to a drilling tool designed with a diameter of 34 millimeters. This size falls into the category of large drill bits, typically employed for tasks that require significant capacity and strength, such as construction work, machinery installation, or even automotive repair. The sheer size of this bit makes it suitable for tasks where smaller bits might struggle, allowing users to drill through thick materials like hardwood, metal plates, or even concrete.
