I may have posted this before, but it just blows me away every time I use it and have to scream from the roof tops
GET SOME OF THIS!
This stuff is for tapping, but it works for drilling and even sawing metal with a hack saw! I cut a bunch of metal tonight, eighth inch angle iron and channel iron. Putting a drip of this oil on the cut then proceeding cutting with the hand hack saw and it goes from cutting metal to cutting a friggin piece of balsa wood! OMG what a difference! Drilling, the drill goes through the metal like it's a pencil through a piece of paper!
Honestly buy some of this stuff!
