The Challenge

The customer manufactures sub-sea petroleum manifolds using a Giddings & Lewis boring mill with 250 PSI (17.237 bar) water soluble coolant.

Since this operation consumed half the day, the customer asked Allied for a better solution.

The Opening Drill® drastically reduced the costly machine run time, which ultimately resulted in a decreased cost per hole.
