Cutting oil/fluid

[wben]

Hi does anyone have a home brew receipe for cutting oil/fluid
It will only be used for basic drilling (no bigger than 13mm) into mild steel.
I know i could go buy some but i have a heap of oils/lubricants/fluids lying around that are begging to be mixed up.

there's no chance that it will set alight?

I never seen it, If it does blow it out. Or keep a squirt bottle of water near by.

I would think any lighter oil would work fine. I just use zep pentrating spray and that seems to work fine.
