Description of HHIP 5801 0501 Flute Single Center - Precision Tool for Accurate Machining
Ground From Solid. Center Cutting. Used for slotting, ramping, pocketing and plunging operations. Preferred for small and medium removal rates on soft, tough and long chip materials such as aluminum, copper & brass. Used for general purpose machining of both ferrous and nonferrous materials.
This end mill appears to be properly sharpened and was sharp when I received it. I haven't actually used it on mild steel, but I think it will work too. The central cutting action was also good. Would buy again.
