Dale or Bill,

I was told that a boring bit would yeild a smooth bore.  Is that the same as a reamer, or is it different ? 

The only "boring bits" I'm familiar with are of two types: the cutting
edge of a boring bar - which, if the feed is correct - produces a
finish as fine as a lathe cut; and a "spade" bit (commonly used for
very hard materials) that might be considered the equivalent of a
two flute reamer, depending on whether the sides have been ground
to cutting edges (really rare!).  I wouldn't expect either to produce
the quality of finish required using only a drill press (unless the
operator had a *very* carefully calibrated arm for feeding the quill.)
