Three cone drill bit is currently one of the most widely used types of drill bits in the fields of oil and gas drilling, geological exploration, and water well drilling. Its core advantage lies in its adaptability to multiple types of rock formations and efficient crushing ability. With the structural design of "three cone collaborative operation", it can achieve stable drilling under complex geological conditions and is the core tool for construction from shallow to deep wells.

In addition, there are some large-sized three cone drill bits, such as 26 inches (660 mm), 36 inches (914.4 mm), etc., mainly used for some special large-scale engineering or oil drilling projects.
Rock roller tricone bits applications
Tricone bits are mainly used for large-scale open-pit mining, such as open-pit coal mines, iron mines, copper mines and molybdenum mines, also the non-metallic mines,water well drilling. With the increasing in variety of type, it's also widely used in quarrying, foundation clearing, hydro geological drilling, coring, tunneling in railway transportation department and shaft drilling in underground mines
