Reading another thread on here, it was recommended to use "cutting
oil" for drilling steel. I'm sure there is a specific oil made for
this use, but is it really necessary, or can just plain motor oil or
WD40 be used? I usually dont use anything if the metal is less than
1/8" thick, but the few times I had to drill in thicker metal, I just
spray WD40 a couple times a minute, or have squirted some used motor
oil from a pump oiler can. Is there any reason to spend money on a
special cutting oil? If so, where does a person get it? And what
makes it different than plain oil?

WD40 doesn't work worth a darn. I tried it once when I ran out of
cutting oil. One of the most common uses of cutting oil is in a pipe
threading machine. Go to a plumbing supply store and purchase some.
It will keep the edge of the cutting tool sharp as it keeps it cool
and reduces the friction during cutting.

Cutting oil is different in that it contains EP additived:
http://en.wikipedia.org/wiki/EP_additive

There is also a link at the bottom of that page that will take you to
another wikipedia page about cutting fluids.

If what you're using has been working well for your applications, then
keep using it! The good stuff carries heat away better, and will keep
your drills sharp longer and give you a better finish on the workpiece.

A local industrial supply house would have a good assortment of cutting
oil, or go to McMaster Carr (www.mcmaster.com) and type in cutting oil
or cutting fluid.

Incidentally, for those unfamiliar, McMaster carries a staggering
assortment of stuff, and has the best website on the internet, hands
down. They ship immediately, and have have a liberal return policy.

Type in "screw" for example, and you can walk through selection
parameters one at a time, in any order, until you get to what you want.
