Re: chamber reaming cutting oil?
I like Castrol MolyDee when NOT using a fluid flush setup , at work they buy the Rustlick or whatever and its ok but the Moly Dee is hands down better for harder metals.
I conned a sales rep out of some TapMagic extra thick and its working realy well also especialy on harder metals like Monel and Hastalloy and it doesn't smell nearly as bad as alot of other stuff.
