💡 What is a roughing end mill used for in CNC machining?

End mills are handy tools for removing large amounts of material quickly and preparing the workpiece for finishing. - Roughing passes to rapidly hog out material from hard metals - Best for tough alloys and hardened steels when paired with proper feeds - Improves tool life with heat-resistant AlTiN coating and carbide - Suitable for use in CNC milling, slotting, and surface prep
