Ok I don't need 25ltr lol. A litre or two will last me more than a year, possibly two depending how many metal working projects I take on, and I only apply by hand so I don't need to fill a sump. Rocol cleancut is £20 for 300ml so even buying castrol cooledge will be a big saving.

I generally cut dry on the lathe - but I mainly use carbide inserts & seem to get away with it. If I'm cutting icky steel, I'll use a blob of neat cutting oil every now & then; also when parting off.

I can't cut dry on the mill, I just snap cutters. So I use flood with soluble on the CNC machine, and flood with neat cutting oil on the manual.

I tend to use ally or brass whenever I can ( not a lot these days   :( ) so cut dry most of the time, if drilling or parting off ally' I use WD40 spray, ( Aldi often have cans on offer cheaper than elsewhere, usual disclaimer) for steel I use a mix of Cetus 9 mix of 25% to 75% water ( from previous work) using a squeezy lab bottle, sometimes use neat cutting oil on small items of stainless.
