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 unique design of these bits also contributes to their superior performance. The buttons, which are made of tungsten carbide, are strategically placed on the bit body to create a cutting surface that is both aggressive and efficient The buttons, which are made of tungsten carbide, are strategically placed on the bit body to create a cutting surface that is both aggressive and efficient The buttons, which are made of tungsten carbide, are strategically placed on the bit body to create a cutting surface that is both aggressive and efficient The buttons, which are made of tungsten carbide, are strategically placed on the bit body to create a cutting surface that is both aggressive and efficienttungsten carbide button bits. As the bit rotates, the buttons shear through the rock, breaking it into small pieces that can be easily removed.
