The Challenge

Trying to keep up?

An increase in demand created a need for improved processes for our customer who machines fluid transfer couplings for the oil and gas industry. Their previous tooling was successful, but they were looking for a better cycle time.

Hoping to improve their performance and lower costs, the customer tested Allied’s T-A Pro Drill. Using the “X” high-speed steel geometry insert—designed to provide increased penetration rates and tool life—they successfully decreased cycle time and increased tool life.

When running the T-A Pro, our customer was able to run at higher speeds and feeds leaving them with a 20% increase in penetration rate. The increase in penetration rate while also increasing tool life led to almost 50% cost per hole savings.

The success of the T-A Pro in this application is just another example of why the T-A Pro is more than your typical spade drill.
