A company gave me this drill press.

I will actually use it instead of scrapping, and my question is, is
it
better to use soluble coolant, or cutting oil on it.

thanks

For your needs, used motor oil will be perfect!

Used motor oil may contain heavy metals like lead from the bearing
shells and combustion byproducts suspected of causing cancer.

I think that Tom was being his funny/facetious self. d8-)

I'm wondering what Iggy is going to drill with a heavy-duty,
three-head production drilling machine.

Is he going into competition with Caterpillar?


Tom has a great sense of humor. I am windering if I can just use
hydraulic oil for cutting. I have large quantities of it and even burn
it for winter.

If you're asking me, I have no clue. And if you called a hydraulic oil
company and talked to their top engineer, I'm reasonably sure they
would have no clue, either.

If you want to talk about what properties you want in a cutting oil or
other cutting fluid, I can offer the basics. But it's a tedious
subject and I'm not going off on it unless you want to get into it.
