I had a talk with the HSMadvisor maker, so it seems i had that functionality but did not know how to find it.

So according to the calculator it seems drill / HSS/ or mill/carbide/ is almost the same feed rate. But if drill is cobalt or carbide then 1.5x faster. 1000mm/min and 1500mm /min respectively.

I use the general option " Other non ferrous alloys" in stead of "low lead brass " or similar as the latest give me too slow feed , slower than aluminum. So it seems my brass is different, as i know for a fact that it machines and drills much faster than aluminum.

Will experiment tomorrow to see how fast it could go in real life and report back.
