The Challenge
The customer manufactures valves for the oil field industry using a custom-made spotting drill machThe customer manufactures valves for the oil field industry using a custom-made spotting drill machine running with 60 PSI (4.137 bar) water soluble oil coolant. They are machining a valve body made from WCC cast steel.

In order to improve the production process, the customer needed to eliminate the costly tool regrinds and reduce the large amount of tool set-up time.

The Original T-A eliminated tool regrinds, reduced tool set-up time, and increased the tool life.
