WholesaleAPI rotary mining well tricone drilling bits for very hard formations. The bit description of IADC:735-TCI sealed roller bearing bit with gauge protection for extremely hard and abrasive formations. The details of compressive strength of IADC735 bits are as following: 100-150 MPA 14,500-23,000 PSI The ground description are as following: Hard, well-compacted rocks such as :hard silica limestones,quarzite streaks,pyrite ores,hematite ores,magnetite ores,chromium ores,phosphorite ores,and granites. We can offer mining tricone rock drill bits in a variety of sizes and most of IADC Codes.The details are as following:BIT DESCRIPTION: IADC735-TCI sealed roller bearing bit with gauge protection CUTTING STRUCTURE: Conical on gage, ogive and ovoid on inner rows. Designed for hard and abrasive formations with high compressive strenghts such as granite,limestone,sandy sandstone,dolomite and chert. Application:43,000-52,000Psi SHIRTTAIL PROTECTION: Hardmetal on lug; Wear resistant carbide on shirttail lip and lug. PRODUCT SPECIFICATION: IADC Code:735 The Bearing Type of IADC735 tricone bit is Roller-Ball-Roller-Thrust Button/Sealed Bearing Cutting Structure: Inner and Nose Rows:Ogive and ovoid. Gage Rows:Conical Gage Bevel Protection:Round Choose the proper rocks drilling bits is very important before starting project. In drilling project, Far Eastern have 15 years and more than 30 countries services experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including coal mine drilling,copper mining,iron ore,gold ore and so on.The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of drill bits. We can give our engineer's solution when you can supply specific conditions, such as hardness of rocks,types of drilling rig,rotary speed,weight on bit and torque.
