IADC: 415 - TCI standard roller bearing bit with gauge protection .The formations is soft with low compressive strength and high drillability. A tricone bit is a drill bit with a head that is divided into three main parts. The tricone bit consists of three rotating cones working inside each other and each with its own row of cutting teeth. We welcome you any requirement, we have an experienced team that can provide you a total drilling string solution for your drilling.
