Literal statement:
The Aero-Tech three-flute design has been developed for cost efficient machining of general steels, stainless steel, high alloyed steels as well as titanium and nickel alloys. All Aero-Tech End mills have micro corner protection for extended tool life. Available in coated or bright finished as stocked standards. 
Feature:

• Suitable for high speed machining of aerospace aluminum alloys

• Ultra-fine cemented carbide, high wear resistance and toughness.

• Special symmetry design and precision with balance N=25000RPM, G2.0 good for high speed cutting.

• HJA650 the feature inner coolant holes that provides more effective cooling action with cutting zone for high speed machining.

• Unique sharp cutting edges provide increased performance in smoothness efficiency and finishing.

• Extremely high efficient  cavity milling with metal remove rate up to 800cc/min.

Attention:

1. Make sure work piece and machine are stable and use a precision holder.

2. Please adjust the speed,feed and cutting depth according to actual cutting conditions.

3. The milling conditiongs are for an end mill where the tool overhang length is less than 4*D(mill dia). When the tool overhang length is longer, please adjust the speed,feed and cutting depth.
