Someone was talking bout a water based cutting lub for machining 80% lowers recently. Anyone have info on it??
I use Blaser swisslube, it’s what we use on all our machines, if you are machining it on a conventional mill I would suggest a cutting oil like LPS or MagicTap, it has a tendency to stay on the cutting tool and has real good lubricity. It’s what we use for conventional machining.
