Features and Applications

Steel body

Use high-quality steel to make the base material of PDC bit, the surface of the blade weld high-performance wear-resistant materials,the use of computer software for the overall design of Asymmetric double teeth straight blade ,medium parabolic crown,long gage shape structure .Cutting structure design using force balance,cutters rational arrangement of different structures in different locations of the drill, drill  effectively inprove the offensive and anti-abrasive, a substantial increase drilling speed. The application of fluid dynamics analysis and numberical simulation of flow fied analysis techniques to the design of hydrulic nozzle angle and position of numerical simulation using finite element analysis method, so that the effect of jet carrying rocks and water jet assisted rock to achieve optimal results.

Soft formation with low sticky layers  and low compressive strength,such as Clay,Siltstone,Sandstone.

Advantage

1.Hardened Alloy Steel base material       

2.High performance PDC-Cutters                                               
3.Carbide and Diamond gauge protection                                        
4.Carbide/Diamond Shock Studs                                              
5.Threaded or Plain Carbide Nozzles for Flushing                                

Production process

Steel body

  Steel body fixed cutters are made from a high alloy steel. Advanced machining technology has improved the manufacturing precision remarkably.Great with advanced 9 axes ,5 axes and 3 axis digital mills.
