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.

The YT29 drilling technique employs a dual-axis rotary drill bit, which allows for more efficient drilling compared to traditional methods. The drill bit is capable of rotating at high speeds while simultaneously translating vertically, enabling it to navigate through challenging geological formations. This dual-axis movement results in a more consistent drilling process, reducing the risk of stuck pipes or wells.
