   DCDMA SERIE DOUBLE  TUBE CORE BARRELS
   
M series double tube core barrels was developed as a solution to the ever present problem of recovering a high percentage of  core when drilling badly fractured or broken stratas or soft and friable material that is easily eroded by the circulating fluid. Mud or water can be used with this core barrel while drilling. It has more sturdy design when compared to the metric series core barrels.
