Carbide Endmill, E476 R40/42 Ti, Extra Long- Harmony, 5 Flute, VHM-Ultra, AlNova for outstanding oxidation resistance and hot hardness. 

This is the best solution for trochoidal milling strategies, as the 5 flute design
provides the optimal productivity when considering Metal Removal Rates (min/cm3). Longest tool life is through a combination of specialised carbide
grade, geometry that suppresses chatter, ultra smooth surface finish for cleaner cutting of the material and a specific PVD coating developed to resist wear in machining titaniums. The component quality is very high without burrs, even when taking semi‑roughing type cuts.
