1、Double rows five blades design, significantly increases wear resistance and stability of the bit.
2、Deep blade design ,lessens the torque, increases the footage capability and rate of penetration 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、Enhanced gauge with high quality PDC cutters, helps several-fold increasing wear resistance and life of the bit.
5、The surface of the blade is welded by wear-resistant hardfacing material, improves wear resistance and erosion resistance of the bit.

Features:
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 abrasiveness, such as limestone, sandstone and shale, etc.
