Product Description

Wholesale mining well tricone drilling bits with discounted price from China factory.
Bit Description:
IADC: 722 - TCI standard open air-cooled bearing roller bit for hard semi-abrasive and abrasive formation.
Far Eastern rotary drilling bits includes geometries and cemented carbide grades for different surface and compressive strengths, abrasiveness, massiveness and homogeneity of rock as well as for various penetration rates and capabilities and characteristics of the drill rig. Innovative bearing technology and improved geometry, materials and machining methods provide longer bearing life.
The selection of Far Eastern Drill rotary drill bits covers both blast hole bits for mining applications and bits suitable for construction and civil engineering applications. The product covers hole diameters from 159 to 406 millimeters (6 ¼ to 16 inches). Both air-cooled and sealed bearings are available, as well as various carbide grades and insert geometries with cutting structures optimized for all conditions.

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.
