"John was so impressed with our equipment and helpfulness that he agreed to purchase a second Symmetrix system including a second COP 54 hammer based on our recommendations, on the spot."
The operators were slightly apprehensive using the new kit in front of an Atlas Copco employee but still managed to have the borehole to the total depth by 12:40 pm. The operator joked that it would take him longer to pull out the casing than it would to drill the hole (it did). I have personally drilled similar ground conditions using the old design of retrievable Symmetrix system N-model and did so for some years, and I can confirm that the new Symmetrix design “is a weapon!”. The increased flushing capabilities dramatically improve the system and from a quality point of view it should be able to sustain a lot more punishment than its predecessor. Even just drilling to 7,5 m on this site I could see a vast improvement. The latching in and out of the ring bit has also dramatically improved with less rotation required due to the 5 no latching points. It seamlessly glides into latched and unlatched positions effortlessly and this was also noted by the operators from Drilcorp Ltd.
