Its soluble cutting oil. You can use kero in an old sauce bottle and trickle it on ir sone people use WD40 if you dont have a coolant system on yiur machine. Parting off requires it as does rurning of a fee materials depending on the tooling you use.

Thanks mate. I've always found WD40 a bit too thin and it seems to evaporate off pretty quickly.
I'll have a look into the cutting oil.
