tools for drilling through rock in tunnels, specifically designed

In the early days, drilling deep into rock was a laborious and time-consuming task. However, with the introduction of extension rods, what once took hours can now be achieved in mere minutes. This leap in operational speed is credited to the rods' ability to transfer energy more efficiently from the drill machine to the drill bit. As a result, projects that once demanded Herculean efforts are now completed swiftly and with greater precision.
