PRODUCT SPECIFICATION:  IADC Code:615 Bearing Type:Roller-Ball-Roller-Thrust Button/Sealed Bearing Circulation Type:Jet Air Cutting Structure: Inner and Nose Rows:Ogive and conical Gage Rows:Conical 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.
