Milling bits and cnc general resources


I´m looking for resources on learning about the kind of bits i should use, what kind is good for this and that, i have been reading on the forums, i must admit i´m a little lost on the terminology. Also i´m interested in general stuff as the kind of cuts you can make, the feed rates and those kind of things.

If any of you could tell me of a book or article i could read so i become more familiar with all things related to CNC millings

A lot of that information is on youtube
