Machining stainless steel parameters

Hi, does anybody has worked out what are the best feeds and speeds for dry cutting SS304 ?
I tried and it works ok, but material and endmill is getting crazy hot, so I am worried if tool would survive making deep holes.
From other topic conclusion I have is ‘no cooling is recommended adjust feeds and speeds’ but slower does not mean better for heat generating issue.
I am using 6mm diameter 2flute VHM tool at random feeds and speeds making 8mm diameter 20mm deep holes and I can’t find any sweet spot between different frequency of vibrations.
With regards,
Piotr
