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.
