Soft to medium hard formation drilling
Medium short parabolic crown profile and medium cutter density helps to obtain better ROP in soft to medium hard formation with lower compressive strength and thin hard layers.
Gauge protection
Gauge cutter improves the gage wear-resistance to prolong the service life of the bit.
Unique backrack design
Unique backrack design helps to reduce the bit torque and increase its aggressiveness.
