My "lat" can of cutiing oil wandered off, so I went to the local Borg to buy some more. All that they had was pints of "dark" thread cuttiing oil (Oatey 30203), so I bought that.
I'll be using it for cutting or drillling iron/steel.
What's the difference? For Harry homeowner, does it matter?

Seems to be the good stuff:
Ingredient # 01 Ingredient Name HYDROCARBON OILS CAS Number 1003 Proprietary NO Percent 0 Ingredient # 02 Ingredient Name SULFUR COMPOUNDS CAS Number 1003 Proprietary NO Percent 0 Ingredient # 03 Ingredient Name CHLORINATED PARAFFINS CAS Number 1003 Proprietary NO Percent 0
FWIW (I have no qualifications to speak of except enthusiasm and experience acquired through a string of failures), I use Rapid Tap for both tapping and drilling. It seems to do the trick on holes up to 3/8" (I seldom do any bigger).

Rapid Tap (trade name) is great stuff, but it gives off a less than desirable plume of fumes if "heated", as by drilling or turning, so watch out.
One of the Rapid Tap products is labeled as being "non-staining" for Aluminum. I've never seen the difference when it is used on anything else, so that is what I use. Same problem with the smoke though!.
Take care.

It seems to be a little better than Crown cutting oil from MSC but not nearly as good as the fancy tapping fluids.

Would that explain the visions I have been having lately?

If you're not smokin', you're doing it wrong! It's the color of the smoke that counts.

The dark stuff has more sulfur in it, eases cutting threads on steel/ iron pipe with pipe dies. Also reacts with aluminum, so don't use it for cutting that. A good choice for dabbing on a steel workpiece. Expensive and messy for coolant setups, have seen it used, though. When the workpiece gets hot, it smokes, other inhabitants may not appreciate it. I use it all the time for drilling and tapping harder steels, like guns.
Usually the clear cutting oils rely more on chlorine, kind of does the same job, not as effective, in my opinion, for hand uses on hard steels. This stuff also reacts with aluminum, usually more vigorously.
Lard oil is another good choice, should you find an old-timey hardware store that carries it. Can be found in some of the "green" mixes, it's biodegradeable.
The heavy black sulfurized stuff is hightly recommended as a replacement for the oil lard oil used in the past. I have never found a source for real lard oil so I have no basis for comparison. The black stuff works pretty well on threading. Don't ask me if I think it is worth the mess.
