API rotary roller mining drill bits IADC425 for gold mining
API rotary roller mining drill bits IADC425 for gold mining. We are a factory with high-quality products, competitive prices, and reliable delivery. Trust us for your drilling needs.
Wholesale mining tricone rock drill bits with discounted price from China factory.Bit Description: IADC: 425 - TCI sealed roller bearing bit with gauge protection for soft formations with low compressive strength and high drillability. Compressive Strength: 65 - 85 MPA 9,000 - 12,000 PSI Ground Description: Long intervals of very soft poorly compacted shales, dolomites, sandstones, clays, salts and limestones. We can offer mining tricone rock drill bits in a variety of sizes and most of IADC Codes.BIT DESCRIPTION: IADC:425-TCI sealed roller bearing bit with gauge protection CUTTING STRUCTURE: Chisel on gage,conical on inner rows. Designed for very soft formations with low compressive strengths and high drillability such as shale,soft limestone,sandstone,conglomerate,soft dolomite and coal ore Application:5,000-8,000Psi SHIRTTAIL PROTECTION: Hardmetal on shirttail lip; Wear resistant carbide on shirttail lip and lug. PRODUCT SPECIFICATION: IADC Code:425 Bearing Type:Roller-Ball-Roller-Thrust Button/Sealed Bearing Circulation Type:Jet Air Cutting Structure: Inner and Nose Rows:Conical Gage Rows:Chisel Gage Bevel Protection:Round Choose the proper rocks drilling bits is very important before starting project. Rocks hardness could be soft , medium and hard or very hard, hardness of one type of rocks may be also a little different, for example, limestone, sandstone shale has soft limestone, medium limestone and hard limestone, medium sandstone and hard sandstone , etc. 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.
