Prolong Bit Life
The self-stabilization design reduces the vibration and lowers the damage to the cutters.
High ROP
Unique cutter layout and location can keep cutting edge sharp to obtain the maximun ROP.
Multi-function Hydraulics
The deep-blade design can get high ROP in soft formations and can better cool the bit in the hard and abrasive formations.
