I am going to mill about 100 notches into brass. 1/4" end mill. 3/8" full depth (cannot step down bit by bit to the 3/8"). Have to go through a 3/8" piece. (Will be notching out a 3/8 by 3/8 square by 1/4 wide). What end mill would be best? I am guessing a two-flute, like for aluminum but is there something better?

I was wondering what the best machine and setup would be to cut a thin slot, .020", about 1/4" to 3/8" deep, into brass bar, maybe 10"-14" in length. I was thinking a slot saw blade or a micro drill bit. Would a horizontal mill or vertical mill be better? From what I have gathered it seems like a vertical mill is more versatile.

The max depth you should use in a slot cut is the diameter of the end mill, so for a 1/4" OD end mill, you can cut 1/4" deep at a time. If you need to go deeper then make multiple passes. The max axial depth of cut, meaning the max amount of the end mill that is touching the work when doing profiling cuts, is 1-1/2 the diameter of the end mill.

Keep a low cut width (or cut depth if you're talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 2-3x chip load will be right for the finish pass.
