1、Single row spiral five blades design, significantly increases wear resistance and stability of the bit.
2、Unique gauge with high quality PDC cutters, helps several-fold increasing wear resistance and stability of the bit.
3、optimized waterway design is ensured with the hydraulic configuration of the bit, balances fluid flow, allows effectively cleaning bottom-hole zone, anti-balling.
4、Shock-proof inserts lessens the vibrations while drilling,increases the steady 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 long 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 soft to medium hard formation, such as shale, sandstone, chalk rock, etc.
