Feature Description :

1.Singl row spiral five blades design, optimized waterway design is ensured with the hydraulic configuration of the bit, balances fluid flow, allows effectively cleaning bottom-hole zone, anti-balling.
2.Unique gauge with high quality PDC cutters, helps several-fold increasing wear resistance and stability of the bit.
3.High density PDC cutting structure design ensures efficient reaming and drilling while extending the application and performance range of casing running operation.
4.The surface of the blade is welded by wear-resistant hardfacing material, improves wear resistance and erosion resistance of the bit.

Design Description :
1.Deep blade and medium parabolic configuration design,ensures optimal bottom hole flow pattern and anti-balling.
2.Optimize the cutting structure and places high quality cutters at different points, increases wear resistance and offensive of the bit .
3.Anti-whirl design improves ROP and enhances drilling stability.

Application :
Suitable for medium hard formation with high compressive strength and abrasiveness, such as limestone, sandstone and shale, etc.
