Product Description The 412F airflush core barrel is designed for coring in soft to medium hard rocks using air as the flushing medium. It is often used for open-cast coal exploration and general geotechnical coring in situations where it is not desirable to use air as the flushing medium.The large annular space between the inner and outer tubes, in combination with face-discharge core bit designs, allows a large volume of air to reach the face of the bit . This is essential for cooling the bit and uplifting rock cuttings from the borehole.This core barrel has proved to be very effective when used with PCD core bits, giving a fast rate of penetration and good core recoveryKey to Main Parts of 412F Core Barrel AssemblyComplete core barrel consists of:1.
