C'mon Jazz, where's the fun in doing things properly ?

Brass is the most fun for buggering up tools as it is a soft (ish) but brittle combination and sticks like sh*t on cutters. You need lots of air to clear chips and cool the workpiece and tool and some lube. Brass can be cut with normal 2 flute cutters, but feeds and speeds have to be right. Too slow and you get rubbing and heat and excess sticking on the cutter. Too fast and you can dig in and get a shite finish (before the tool breaks).

Go for it, but buy lots of cutters and acres of brass, you'll get a lot out of it, mainly scrap brass and broken cutters.
