What is the working principle of the 89mm Mring Overburden Concentric Casing Drilling System?
The system works by welding the ring bit and casing shoe assembly to the casing before drilling. The pilot bit's upper shoulder engages the casing shoe, transferring percussive energy to crush rock and advance the casing. After drilling, the drill string is retrieved by reverse rotation, leaving the ring bit in the hole.
