1、Double rows spiral seven blades design, significantly increase swear resistance and stability of the bit.
2、Unique gauge with high quality PDC cutters, helps several-fold increasing the wear resistance and stability of the bit.
3、Additional nozzles is ensured with the hydraulic configuration of the bit, balances fluid flow, cuter cooling and erosion resistance.

Features:
1、Deep blade and short parabolic configuration design,ensures optimal bottom hole flow pattern and anti-balling.
2、Optimize the cutting structure and place high quality cutters at different points, increases wear resistance and offensive of the bit
3、Anti-whirl design improves ROP and enhances the drilling stability.
4、Manufactured with high quality tungsten carbide matrix powder, ensures the erosion resistance of the bit.

Application: Suitable for medium hard to hard formation with high compressive strength and abrasiveness,such as mudstone, hard gypsum, dolomite and sandstone,etc.
