Core drilling rod introduction
The drilling rod adopts the quick connection method of square or hexagon. When used, it is automatically
locked by spring pin. It is equipped with U-shaped or semi-ring type anti-off-pin to make the torque of the
drill pipe reach the best state. This series of products is mainly used with portable or hand-held drilling rigs.
The drill pipe is light weight, quick connection, fast slag discharge speed and greatly improved work efficiency.
It is called high-efficiency auger drill pipe.
The drilling rod are widely used in the drilling of water exploration gas in coal seam and near coal seam
geological conditions, divided into water-passing type and non-water-passing type.
