MECCA Spiral Groove Directional Drill Rod is one kind of directional drill rod. It is made of thick-walled tubes. We mill spiral grooves on the rod body. It creates spiral thrust at the drill rod body to flush the debris efficiently in drilling process in coal mine.
Applications:
Directional long boreholes drilling and water exploration and drainage boreholes drilling in underground coal mines.It can also be used for the drilling of nearly horizontal directional boreholes on surface or in the tunnel.
