High Performance End Mill

How to Select the Right High Performance End Mill for Hardened Steel

In CNC precision machining, working with hardened steel (HRC 45 and above) is notoriously challenging. The material’s hardness and the resulting high cutting forces demand tools with exceptional wear resistance and machining stability. Conventional general-purpose end mills wear rapidly, causing reduced productivity, compromised part accuracy, and soaring costs. Selecting the right high performance end mills […]
