Old timers used Kerosene for a lubricant on Aluminum,that's what I use.
Bicit, I have never used the Non-Fluted taps, or ever seen them, I worked sheet metal fab shop, they
may have used them in the machine/engine shop, but that was another world unto it self.
I just bought a small can of WD-40 to spray down the tools I'm having to buy doing this DYI, gave my
2 rollaway tool boxes and tool to my son when I left the US. Having to buy new toys to make things.

In aircraft aluminum drilling in the shop, we used WD-40 as a lube or paraffin(canning wax).
Don't forget to start with a "starting tap", there is also taper and bottoming taps, sometimes you have
to use two taps to do the job right. Besides backing up when you feel pressure as "Rahz" said, you
may need to back the tap OUT to clean the chips out.
They aren't cheap, but they do make tap extractors, and for big $$$ parts from blueprints, you can't
drill and tap a new hole.

Paraffin wax sounds like an excellent idea. I was using propylene glycol perceiving it to be less cleanup than oil. I ended up buying some drill oil and after some thought I tried pouring a small amount in a shot glass. Application is a simple as dipping the tip of the tap into the oil 1/8-1/16 of an inch, hardly anything to clean.

Careful boys and girls,Fire Marshall Bill says WD-40 is flammable and under pressure and can turn into a flame thrower.
How is this related to drilling and tapping aluminum and removing broken taps?

Just received 2 new taps and they're easy as hell now. They're spiral tap things
