I need to do some metal drilling on the press today but could not find any cutting oil at HD. Can I substitute something like 3-1 oil , WD40 or something else without burning up the bit? I am a novice so help would be great.

Dave, I have used plain 30 wt oil many times over the years. I have a squirt can sitting beside my drill press ready to grab when I start drilling metal. Probably not as good as cutting oil but for typical work, I find it does fine.

Dave, sometimes you can find the cutting oil in the plumbing dep't as it is also used for pipe threading. If none at HD or lowes try a plumbing supply house. If all that fails any light oil is better than none.

Just for reference; kerosene works great for aluminum.
