Over burden drilling system is a kind of system which works in overburden rock conditions. Overburden drilling system has good application on well drilling, piling and geotechnical drilling. And we are able to supply both ODEX and Symmetrix system. The ODEX system is including ODEX 90 ODEX 115 ,ODEX 140 ,ODEX 144, ODEX 165, ODEX 190 and ODEX 240.
Overburden drilling hole Diameter: ODEX-eccentric: 114-324mm
Symmetrix-concentric: 114-610mm
Pilot bit is well designed to offer good drilling efficiency.
Optimization design for each part reduces the probability of accident.
Strengthening quality of stable pole driller extends the drilling life and improve cost-4, performance ratio.
