The Role of the Tail Pipe in DHD Series Down-the-Hole Drill Bits

Guidance and Positioning: As part of the drill bit, the tail pipe serves as a guide, ensuring that the drill bit accurately follows the predetermined path during the drilling process, reducing deviations, and improving drilling accuracy.

Discharge and Drainage: The tail pipe helps to discharge debris, mud, and other impurities generated during the drilling process, keeping the drill hole clean and enhancing drilling efficiency. Additionally, the tail pipe guides the coolant or flushing fluid into the drill bit, ensuring its normal operation and effective cooling.
