For machining in unstable conditions, the recommended cutting data should be reduced by 20-30%
IC830 is a general purpose grade and it may be considered as the first-choice grade
IC845 is recommended for milling at relatively small depths of cut and for interrupted cutting applications
IC5500 is intended mainly for milling ferritic and martensitic stainless steel at increased speed
