But, in a tapping situation, I had never thought of this. If I was in a pinch, I might do it, but it'd be an absolute last resort.

After reading this I thought of something funny that happened to me.
At work I was getting ready to power tap the ends of several pieces of Bosch profile with a 12mm tap. After getting the Milwaukee drill set up with the tap I went into the machine shop asking for a bottle of tapping fluid. Now most of the machinists there keep plastic spray bottles and containers on thier machines or carts and not the original containers. They don't mark most of the plastic containers after transferring contents into them. One of the guys handed me a container and told me "Here's what you'll need". It was blue in color.
After I shot some of it into the ends of the profile and on the tap I preceded to tap the profile as it was clamped to the bench. I'll be darned if the stuff he gave me wasn't the best stuff I've used so far! Usually I'd have to clean the tap off after each hole, instead the chips fell right off the tap as the drill spun in reverse as I removed the tap. The tap stayed real cool also and it had a wierd but yet familiar smell I couldn't place right away. After doing two dozen or so holes he came running out with another container with blue liquid in it. Apparently he realized he gave me the wrong container. I had been using diluted Dawn as tapping fluid!
