  2. Possible to high precision and high efficient machining for aluminum, stainless steel and titanium alloy in aerospace tooling. • Adopting high precision design enabled minimum deflection and high accurate machining • True 90 degrees shoulder milling • Multi-purpose milling is possible: face milling, shoulder milling, slotting, ramping and helical interpolation • Insert has key for high velocity revolution specification • Internal coolant supply • Adopted “G-body” • High metal removal rate: Q=2,250cc/min by 50 dia.(aluminum alloy) 15mm DIJET Industrial Co., Ltd. 2
