1、Double rows spiral five blades design, significantly increases wear resistance and stability of the bit.
2、Enhanced gauge with high quality PDC cutters, helps several-fold increasing wear resistance and life of the bit.
3、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.
