For machining aluminum, use IC20, maximum cutting speed corresponds to the maximum RPM indicated on the cutter A - First choice B - Second choice
Recommendations are for normal machining conditions
If excessive wear occurs, select insert with higher hardness
If chipping or breakage occurs, select insert with more toughness
