Use a very hard grade of carbide that can handle the heat without deformation. Use a high-temp. coating designed for hard milling or high-temp. alloys. Use a light width of cut, typically between 25-40%. Use a light depth of cut, usually between .005"-.015". Use a light feed per tooth, usually less than the T-land width (.003"-.006")

This helps explain why some shops continue to embrace the "rough soft, finish hard" paradigm. When milling hardened material, on the other hand, the machine tool must be very rigid. The insert's cutting edge must be strong and chip resistant. The tool must be running with minimum runout, and the workpiece held as securely as possible.
