Good quality 5inch PDC mining drill bit with 5 blades
PDC cutters of different features are selected and bit profile design is optimized to suit
different drilling applications in different formations to satisfy different requirements when
drilling soft to medium hard 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 matrix body material with self-owned intellectual property rights
and combining FEA analysis technology.
-Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology
to enhance cleaning and colling effects of the bit to effectively prevent bit from balling.
-CNC sintering process uses full automatic control/ Inside and outside temperature of the
bit is monitored during all procedures to fully embody material properties as well as ensure
uniformity and stability of product quality.
