Characteristic of this series bits:
.PDC cutters of different features are selected to suit different drilling applications in different formations.
.Cutting structure is force balanced, non-symmetrical blade and wide gage are designed so that the bit drills more stable and resulting longer working life of the bit.
.Better wear resistance and higher strength of the bit are guaranteed in regard to material and structure by using best matrix body material and combining FEA analysis technology.
.Enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
