I am looking to buy End Mills for Aluminium 2 Flute size 1mm to 8mm. Does anyone know a good source, I would prefer carbide with TIN coating or just carbide. These will only be used for Aluminium 6061 T5. If anyone has a different recommendation then 2 flute let me know. My Spindle goes from 5000 to 24000 RPM and is a 1.5kW Spindle with bearings for metal cutting.
