Product information:
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.

1. Significantly outperforms the successful Series range in
drilling speed and bit life.
2. Protects the diamond from oxidation and surface degradation.
3. Inhibits the premature "pull-out" of the diamond.
4. Available in multiple standard configurations and selected on
the basis of relative rock hardness and ground conditions.
