Soluble oil was what I was supposed to use for tap busting. I'll have to look into keeping the bacteria out. What do you think of using something like Kool-Mist for griinding?
Kool-Mist is probably just fine, I'd make sure you're using the correct concentration for grinding thus the need for a refractometer. Make sure the system is clean to begin with and if it ever does become contaminated thoroughly clean it with a very strong chlorine bleach solution.
One can also purchase wafers/tablets/additives to help forestall bacterial growth. I know Travers Tool carries such products so I expect they are also available from any supplier that sells cutting fluids. Some just add bleach which is not a good idea as it really screws up the Ph level and contributes to rusting.
