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.

Coal drill bits come in various types, each tailored to specific geological conditions and drilling needs. The most common types include button bits, tungsten carbide insert (TCI) bits, and steel-to-steel (STT) bits. Button bits, with their carbide buttons on the surface, are ideal for softer rocks and coal seams due to their excellent wear resistance. TCI bits, on the other hand, are more suitable for harder formations due to their tungsten carbide inserts that provide exceptional toughness and wear resistance. STT bits, made entirely of steel, offer a cost-effective solution for less demanding drilling applications.
