Impregnated Diamond Bits

Impregnated diamond bit

The synthetic diamond polycrystalline is manufactured by sintering the fine grains of synthetic monocrystals 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 usd 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,hydrogeological exploration and building construction,ets.
