Product Description
Tricone bit is a rock drilling Tool with tungsten carbide insert used on the rock oil mining water or oil well . This rock drilling tool is manufactured according to API specs which are the API certification products. . Tungsten carbide material is very hard material which hardness is only lower diamond in all the material . Comparetely the Diamond drill bit , Tungsten carbide drill bit price is lower .Tricone drill bit is called roller cone bit according to API standard .
Tricone bit is used tungsten carbide material Tooth to cut the rock which are split two type roller cone bit welding TC Milled Tooth and TCI Inserted .
TC Milled tooth and TCI inserted drill bit are customized Drill Bit according to the Rock grad. TCI Tricone bit is used for the middle hard to hard rock formation.
Milled tooth (all called steel tooth) tricone drill bit is used for soft to very soft rock formation.
This drilling tool is widely used in the mining well (such as coal mines, copper mines, and other rare metal mines),water well , oil /gas well and geological prospecting .
