I've been on this kick of using up stuff ive had around forever. The latest victim is a bottle of mineral oil i purchased to stain soapstone. This is the stuff you buy at the pharmacy.
The only real use i could come up with was as stated drilling and tapping. i only tried it for a for a .156 bit and 10-24 tap about a 3/4" deep hole. i compared napas house brand, castrol moly d and re-li-on.
as far as drilling went the only differences i noticed was that the mineral oil was about 1/4 the cost of the others and no chlorine smell.
tapping was different. breaking the chips was a little spooky with mineral oil and 4 flute tap but then again that i think is a little due to the design but it was very different than with the specific oils. with two and three flute taps i didnt notice much difference.
