I mistakenly ordered some and it was water based, never again, seems more corrosive than Nitram. Failing that I use just light oil.

Usually use engine oil with pillar drill but would buy cutting fluid frm Machine Mart if I wanted some proper fluid.

What material are you cutting, and what with?
We use a variety of cutting oils and water-based MWF's at work, mostly oelheld stuff.

Bought 2 aerosols of this a couple of years ago, great for all metal working at my level. ie drilling, power hacksaw etc.

Been using a cheap water soluble cutting fluid from RDG tools on the lathe. Seems to be prohibiting rust quite nicely on the machine considering how rarely it's used.

I may well burn in hell for this but I don't use any on my bandsaw. Can't claim to do tons of cutting but not seen a reason yet to change.

Ideally you'd want a flood coolant system using MWF, it makes a huge difference to how long the blade lasts. Cheapskate version is a 10L pressure sprayer full of MWF used as a poor mans Kool Mist (a trick used by my oppo at job #2 who is too cheap to buy a flood coolant system)

Think I've mentioned this on here before, but I'm a member of a US based forum where one of the members is a chemical engineer who's specialty is cutting fluids.
He's adamant that for mild steel in anything less than a production environment (ie where the saw has someone running it all the time) that bandsaw coolant isn't worth the money and mess.
he would advocate spending more on blades like lenox than on coolant.
Exceptions would be where large solid bars or stainless are being cut. if they're only occasional then a squirty bottle is more than enough.
i use cooledge BI bought by the 20 ltr can. most times just used out of an ordinary oil can

Flood coolant does more than keep things cool - it helps with chip clearance & results in not only a better cleaner cut, but also helps prolong blade life. Squirty bottle on a bandsaw is much less useful & in many instances worse than nothing because the fluid gums up around the blade resulting in poor chip clearance.
Can’t see how a flood coolant system is too expensive.
Weld up a base/tank and a pump and a few pipes.
Central heating pumps work great.
I’d not fancy breathing in coolant mist too much.

and throw a magnet in the sump to collect out the smallest bits of steel to prolong pump life.
