Water Well Drill Bits Description
Water Well Drill Bits is one of the main tools for blast hole and water well drilling. Its life span and performance whether suitable for drilling or not, that has an great influence about the quality, speed and cost of drilling project. The rock breakage by the tricone bit which used in mine is working with both the impact of teeth and the shear caused by slippage of the teeth, which bring high rock breaking efficiency and the low operation cost.

Water Well Drill 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
