PDC bits

Matrix /Steel Body PDC Bits are suitable for directional drilling.
Characteristics:

-Shallow core and short gage design make the bit having better steerability to satisfy and demand of directional drilling applications.
-Optimized profile design and denser cutter layoutat should are can grarantee higher side cutting ability of the bit.
-Inclined gage drsign to increase the bit's ability of gage protection.
-Optimized hydraulic design for increased cooling and cleaning effects of the bit in horizontal and directional sections and therefore,to prevent bit balling and improve ROP to the bit.

High End Matrix Body PDC Bits (type KMH)are suitable for medium and medium hard formations.
Characteristics:

Specific to characteristics of hard formation and interbeded formation,bit profile is optimized and cutting depth of the bit is controlled.
-Overall performance of PDC cutter is improved by using high performance PDC cutters of better wear resistance, better impact strength and better thermal stability.
-Unique cutter layout and specific force balance analysis plus other related technologies,etc.improved the bit's working life and premature ring type wear of the bit is prevented.

-Optimized hydraulic design can improve the bit's cooling effect and therefore, prevent PDC cutter failure caused by high temperature.
-Bit diameter shringage is effectively prevented by enhanced gage protection design.

PDC Core Bits (type KMC )  are high performance core bits .

Characteristics:

-Arc type crown design and blade type cutter layout result in high ROP, high core recovery rate and long working life of bit,etc.
-Use both PDC cutters and diamonds for gage protection for extened bit life.
-Dynamic flow simulation technology is employed to optimized hudraulic design of the bit and enhance the bit's cleaning and cooling abilities.
-Inner and outer diamond gage protection. The water course is located at inner gage protection and consequently, cutting elements can receive sufficient cooling and cleaning.
-Force-balance technology is used to improve stability of the bit and prevent the bit from balling up.
