Product Details

Borehole Geological Drilling Impregnated and Surface Set Diamond Core 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.

1.1 Heat treatment control:

Heat treatment will greatly improve the material strength and increase the thread wear life

of the rods and casings. We conduct either tru-wall or both ends heat treatment to the

tube body. After heat treatment, strength, hardness, straightness and concentricity of the

treated tubes will be tested in our lab.

1.2 Thread opening process:

Accuracy of threads will determine the use effects and life time of drill rod and casings.

CNC latches and form cutter are used in thread opening processing to minimize error

made by anthropic factors.

1.3 Additional thread treatment:

Surface of the threads will be cleaned to remove burr adhered after threads are opened.

Afterwards, the tread surface will be phosphated to improve surface conditions.
