Another important feature of tapered rock button drill bits is the placement of rock buttons on the bit. These rock buttons are typically made of hard tungsten carbide material, which is known for its excellent wear resistance and durability. The rock buttons are strategically placed on the drill bit to provide maximum impact and cutting power, allowing for efficient rock penetration and faster drilling speeds

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.
