Boring holes on a mill is very similar to boring holes on a lathe except the cutting tool moves rather than the part.  The main advantage of boring over drilling is that the hole will always come out in perfect alignment with the spindle whereas a drill may "wander".  Larger holes must be bored rather than drilled on a small mill because large drills cannot be chucked in a Unimat and it takes horsepower to drill holes over 3/8".  Using a boring head, holes up to 1" can be accurately bored.
