Atlas Copco Secoroc have been continuesly improving the Casing advancement system. Today, we have developed a new face design for Symmetrix and Elemex and found a way to allow both Symmetrix and Elemex pilot bits to use the same ring bit set. With this new concept Atlas Copco Secoroc will turn the product selection easier.
The new face design (patent pending) of the Symmetrix and Elemex pilot bits improves the flushing of the cuttings that makes the penetration rate even better than before, especially in clay and sand formations. When changing the pilot bits you only need one ring bit set for both pilot bits, and you will save time as well as money. This is an extra advantage when sensitive ground is encountered.
