SOFT TO MEDIUM HARD FORMATION DRILING
Short parabolic profile with lower cutter density helps to obtain better ROP in soft to medium hard formations with lower compressive strength and small hard layers.
DURASET GAUGE
Super strong material promotess gauge wear resistance to provide long bit life.
SPECIAL CUTTER LAYOUT
Balanced force cutter layout combined with straight blade design to improve the bit stability.
HYDRAULICS
Big junkslot with balanced hydraulics design improves anti-balling ability within high penetration.
UNIQUE BACKRACK DESIGN 
The cutter's backrake has been unique design, reducing the bit torque and increasing aggressiveness.
