Product Detail/Description

Features and Applications

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 helical gear cutter blade,long parabolic crown structure.Cutting structure design using the force balance, cutters rational arrangement of different structures in different locations of the PDC bit,using high -quality cutting teeth,the medium increase local equivalent density cutters cutting teeth,improve the resistance and drill attack abrasive. The application of fluid dynamics analysis and numerical simulation of flow field analysis technology to the design,maximum the flute area and multi-nozzle design, the effect of jet carrying rocks and water jet assisted rock to achieve optimal results,but also good clear and cool the PDC bit.

Suitable for high compressive strength,with abrasive medium hard to hard formation,,such as shale,limestone,anhydrite,sandstone and so on.

Advantage

PDC Cutters 

We had very good relationship with the PDC Cutter factory in the world ,Like USS ,E6,Smith ; And discuss the cutter technology and long term cooperation and relationship. So that we can improve our PDC drill bits performance , drilling faster and lower cost. 

double row cutters

The maximum local cutters equivalent density, improve the offensive and abrasive resistance of the bit in hard and abrasive formation.

gauge cutters

High quality arc PDC cutters gauge, reduce the abrasion of rock on the bit's body, increase wear resistance and stability of the drill gauge.

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.
