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 (1) For workpiece materials list, see pages 728-757
