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.

A rock drill shank adapter, as the name suggests, serves as an adapter between the drill shank, which is the primary working end of the drill, and the drill rig. It is designed to withstand the immense forces exerted during drilling operations, translating the rotary motion from the drill rig into percussive energy that breaks down rocks and other hard materials. The adapter acts as a bridge, enhancing the transfer of power while minimizing wear and tear on both the drill bit and the machinery.
