9-1/2” GD1307
MEDIUM HARD FORMATION DRILLING
Medium parabolic profile with medium cutter density helps to obtain better ROP in medium hard formations with medium compressive strength and small abrasive layers.
DURASET GAUGE
Super strong material promotes gauge wear resistance to provide long bit life.
HYDRAULICS
Cuttings removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each balde with the proportional fluid flow.
UNIQUE BACKRACK DESIGN
The cutter’s backrack has been unique design, reducing the bit torque and increasing aggressiveness.
