Tricone bit IADC835 is TCI sealed roller bearing bit.The bit has gauge protection. The cutting structure are as following: Ovoid on gauge and inner rows. The tricone bit will be used for extremely hard and abrasive formations with high compressive strengths such as granite,quartzite,magnetite quartzite. The application is from 55.000Psi to 66,000Psi. The shirttail protection is hardmetal and wear resistant carbide on shirttail lip and lug. The bearing type is roller-ball-roller-thrust button/sealed bearing. The circulation type is jet air. Far Eastern Drilling in 2008,attained the quality certifications of API and ISO.As a leading drilling bit factory,we currently hold the majority market share in Chinese domestic market and convincing marekt shares in the south American markets and Australasian.
