          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
