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
