I am just getting into some metalworking projects, and will be doing a

I heard that it is best to use "cutting oil" to facilitate the cut and
to prolong the life of the bits. However, a quick search on the web
shows that prices start at about $14 per gallon. Are there any
alternatives which will do the trick, but not be as costly?

A gallon of cutting oil will last you a good long time.

How about
motor oil?

Not as good, and not much cheaper.
