SOFT TO MEDIUM HARD FORMATION DRILLING 
Medium short parabolic profile with medium cutter density helps to obtain better ROP in soft to medium hard formations with lower compressive strength and small hard layers.
DURASET GAUGE
Gauge cutter promotes gauge wear resistance to provide long bit life.
HYDRAULICS
Cutting removal 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 BACKRAK DESIGN
The cutter's backrock has been unique design, reducing the bit toeque and increasing aggressiveness.
