High quality Top sale diamond core drill bits for hard rock mining
NQ HQ PQ diamond core bit Core Drilling Tools
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.
