Any tips for deep slots/profiling in aluminium?

I think M_C your biggest problem will be spindle speed with small tooling as most mills don't spin fast enough for smaller tooling and Deep.

Looking in my Cutwell catalogue the spindle speed for 3 flute 5mm HSSE coated Slot mill is 8200rpm and 610mm/min but with only 0.5 x D.
2 flute would be 6300 and 310mm/min same 0.5 x D

Going to uncoated Carbide 2 flute would be 6400rpm and 320mm/min but with 1 x D.

3 flute rippers will let you go 1.5 x D but they still need high rpm and I can only see them at 6mm no less. I use Carbide rippers all the time and they shift some material even with my WC 2.2Kw spindle so if you could get away with usinfg 6mm they would do the job.
