Up spirals are good for chip removal and smooth bottom edges on
Down spirals are good for pushing the stock down, smooth cut bottoms,
and smooth top edges.
I use 'em both (in solid carbide) in a CNC router; but only when I
need one or more of their particular strengths - otherwise I prefer
straight (HSS with carbide edge) bits because they're less expensive
both to buy and to have re-sharpened.
