Please excuse the naive question... but I read about spiral cutting
router bits hither and yon. But what is the upside? Downside? Are these
plunge bits for the router table? And where's the best place to get
Depends on what you mean by "best". :-) If you're looking for high quality,
never mind the cost, go for Whiteside bits, available at various places. If
"best" means "best value", it's hard to go wrong buying from Lee Valley.
Woodcraft's house brand is decent quality, too, at an affordable price.

: Smoother cut, because they slice diagonally.
There's also upcut and downcut spirals. Upcut pull the
wood in the direction of the router, downcut do the
opposite. Pick whichever one gives less chipout on
a show face.
I've also seen double-cut types, which are downcut halfway
and then switch to upcut.

Before you do, look at 2 flute, aluminum cutting carbide end mills. They are
made for milling aluminum in a milling machine. Identical to spiral router
bits. Generally of higher quality and lower price.
Not the ones I'm familiar with. They're not made for wood, but for stouter
material which removes in smaller pieces.
Sort of like a hacksaw, which will certainly cut wood, but it's no match for
I have a 1/4" bit I use in a router table for cutting dadoes for plywood and
Usually works pretty well as it removes the chips as you go, where as a
straight bit usually
leaves a slot full of dust and chips behind.
One word of caution though.... hold on to your work piece, firmly.
Mine has a tendency to pull the work piece through and sometimes away from
generating less than desireable results.
There's also an 'up cut' and a 'down cut' version of the spiral bits.
