SOFT TO MEDIUM FORMATION DRILLING
Parabolic profiile with mediun to lower cutter density helps to obtain better ROP in soft to medium formations with low compressive strength and small abrasive layers.
DURASET GAUGE
Super strong material promotes gauge wear resistance to provide long bit life
UNIQUE BACKRA DESIGN
The cutter's backrake has been unique design, reducing the bit torque and increasing aggressiveness.
