The synthetic diamond poly crystalline is manufactured by sintering the fine grains of synthetic mono crystals and at high temperature and high-pressure.Because of their advantages of high wear ability,hot hardness high compressive and impact strength,It is widely used in geological exploration,petroleum drilling,mechanical processes,and so on.
Diamond core bits are widely used in the drilling for geological exploration,water conservancy and power engineering,hydro geological exploration and building construction,etc.
