    PDC bits

    1 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

    2 Duraset Gauge

    Super strong Material promotes gauge wear resistance to provide long bit life

    3 Hydraulics

    Cutting removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with the proportional fluid flow
