C908 4-flute roughing end mills have a medium length flute design with an NRA profile for efficient chip breaking when roughing.
The 35 degree helix reduces vibration and shows an improvement in performance when CNC machining, whilst the Alcrona coating further improves performance when milling difficult to machine materials, and increases the life of the tool.
With the great performance and tool life you get from the powder metal High Speed cobalt, used in manufacture, C908 roughing end mills really are a versatile choice and are suitable for roughing operations in steels, stainless steels and cast iron, when plunging, ramping and profile milling
