Tci tricone bit: Tungsten Carbide Inserts tricone bit is also called tci tricone bit. Because of its versatility and performance, it's still one of the main Rock Bits in use today. It is widely used for oil&gas, water well, geotechnical, environmental, geothermal, construction, exploration and mining drilling.

Steel tooth bit: Steel tooth rock bits or named as milled tooth rock bits, can be called as MT rock bits which are manufactured with superior quality steel and advanced technologies, designed for use with compressed air or fluid circulation systems. Steel tooth bit surface apply welding new wear-resisting material in keeping steel tooth tricone high mechanical drilling rate at the same time, improve the bit cutting tooth life. It is widely used in soft to medium formation.

Pdc drill bit: Polycrystalline diamond compact bit is short for pdc bit. Polycrystalline diamond compact (PDC) cutters enhance the performance of PDC drill bits, making them dynamically stable across a wide range of demanding vertical and directional drilling applications.
