Matrix body PDC bits have better wear resistance than steel body PDC bits, they are  suitable for very deep well drilling, especially for the horizontal directional drilling section that depth exceeds 2500 meters.

As the development of hard-facing technology, steel body PDC bits become to be higher wear resistance, steel body PDC bits are used more and more by its higher ROP, safer drilling and lower cost. But in very deep horizontal directional drilling section, matrix body PDC bits still have advantage of longer working life to avoid bit replacement.
