STRATEX™ Eccentric

About the STRATEX™ Eccentric

The STRATEX™ ECCENTRIC DTH Under Reaming utilizes a single one-piece billet DTH under reamer and pilot bit that moves outward to full open position by rotating a half turn clockwise making the reamed diameter lager than the casing.  Allowing the casing to be simultaneously advanced as the ECCENTRIC DTH Under Reamer drills.  Once the desired depth is reached the ECCENTRIC DTH Under Reamer bit can be retracted in to the casing by applying slight tension and rotating counter clockwise which moves the ECCENTRIC DTH Under Reamer bit to it fully closed position for removal of the entire drill string.  This allows for the casing to be left in place for the next operation or removal at a later date.
