Anything is fine with TiN or cobalt bits. Even dry for soft, thin steel like hinges.

Deep drills, hard material, etc, the fluid starts to matter, but not so much for small stuff.

Any metal cutting job benefits from lube, tap magic, 3-1 oil, hell, even Crisco or Astroglide.

Lube is not only for the cutting edge, but helps the flutes on a stupid 0.54$ drill bit clear the cuttings.

So you are saying I should swap Crisco for my Astroglide when I’m doing some hardcore drilling?

I just use a little spit for a small job like this. It's nature's lube. Works surprising well for what is it lol.

truly. it makes the difference between caring about how many holes your tap can make before replacing and not caring at all

When drilling you make a mess anyways

Mess always has to be cleaned anyways

You have to dispose of your drilling mess anyways (you sure dislike making a mess that you have to mention it thrice, diy might not be for you)

Its not a waste if it does something (it does if not much)

Instead of 'worrying', see it a case of good practice.

Is oil 'required' for this? Well no. But it certainly wont hurt anything other than your fear of having to clean up after :p

Bar soap works well, with no mess...

would 91% isopropyl alcohol work to clean off any residue left by 3 in 1 all temp silicone lubricant? Or what works?

In your position I would do it dry, but if I used lube, I would just wipe the hinges down really good with a rag or paper towel and call it good. If you are painting them or something then you need to clean them thoroughly, otherwise it doesn’t matter as long as it isn’t dripping off.

if you are really in a pinch, just use dish soap to clean everything after. That will cut the remaining oil. probably just wiping with a rag after would be plenty good enough.

Dish soap? You must like your hinges rusty. Paper towel to clean off the excess oil and the hinges would benefit from anything else left on it.

Lol whoops forgot it was a hinge. Yeah don’t put them in water.

Not really. Oils are oils, alcohols are alcohols. Alcohol wouldn't do much more than water. Oil can readily be dissolved in lighter oils (mineral spirits) or even WD-40, in a pinch. From there, you can just use soapy water, or degreaser if you have it. You can also try dishwasher detergent, which is often sodium hydroxide, but then you gotta worry about rusting your part. Bottom line - just use soap and water. If that doesn't do it, slather it up with WD-40 and then try to wash it off with soap and water again.

Oh it's silicone? Silicone lubricant is not good for drilling at all. It might work before the bulk solvent evaporates but yeah find something else.

Also you are using titanium nitride coated Cobalt steel drill bits, you 100% do not need any cutting fluid for this small job. And just like a knife, drill bits can be easily sharpened and reused.
