Tricone drill bit is a rock drilling bit with tungsten carbide insert used on the rock well such as :oil mining water or oil well . ,We also call it rock bit ,tungstern carbid bit . This rock Bit is one of the specail rock drilling tool .It is manufactured according to API spec and certificated by API . Tungsten carbide material is very hard material which hardness is only lower diamond in all the material . Comparetly ,the Diamond drill bit , Tungsten carbide drill bit price is lower . Tricone drill bit is called roller cone bit accroding to API standard .
Tricone bit 's are tungsten carbide Tooth or tungstern carbide welding on the tooth . So it was split two type roller cone bit welding TC Milled Tooth and TCI Inserted .
Milled tooth tricone bit and TCI tricone drill bit are customized Drill Bit according to the Rock grade or the API specification IADC CODE . 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 fromation .
This drilling tool is wided used in the mining well (such as coal mines, copper mines, and other metal mines),water well , oil /gas well and geological prospecting .
TCI (Tungsten Carbide Insert) and Steel Tooth Tricone Bits. Each type is uniquely designed to tackle specific drilling challenges and geological formations with precision and efficiency.
