STRUCTURE AND CHARACTERISTICS OF HYD200
The HYD200 drifter is composed of an impact assembly and an independent rotation assembly.
Development history of HYD200 Hydraulic Drifter
The HYD200 hydraulic drifter was produced by the Lianhuashan Metallurgical Machinery Plant of China Nonferrous Metals Industry Corporation after the introduction of technology of HYDRASTAR200 hydrauli
How to choose button bits
The market competition of drilling tools is fiercer and fiercer, and the quality difference of the button bits from different factories is smaller and smaller.
The elements included in body steels and the functions thereof
Carbon (C) mainly affects the strength and hardness of steels. When carbon content is too high, the toughness and welding performance of steels will be reduced. The increase of carbon content in steel
The requirements for the bodies of drill bits
Contacting and breaking rock during operation, drill bits are subjected to huge impact loads and abrasive wear. As application conditions are extremely severe, the requirements for body steels are al
