And Faster Production


When an ATI Stellram customer tested HardCore® Technology, the results were immediate.  The customer's production requires extensive drilling in hardened steel (Material 4140 300Hb). This is a manufacturing challenge to keep speeds up. 

So when the customer's engineers switched from their current high performance drill to HardCore® Technology, the goal was to significantly increase production speeds.

The results:  814 holes in just over 34 minutes, with one drill.  That's compared to 814 holes in 1.1 hours using three drills with the old tool supplier.
