For some time I have been using an aid when drilling holes in aluminum but don't recall seeing this mentioned on the list. I'm probably the last one to figure this out, but in case I'm not, let me introduce you to a cutting fluid called "Tap Magic". This cutting fluid is fantastic stuff.
Tap Magic is truly a great product. Although I have drifted from the Aluminum formula and have begun to use the Tap Magic Formula 1 Biodegradable Aqueous McMaster# 1043K52 on the painted panels. I was afraid that the Tap Magic Aluminum which is a petroleum distillate product, might damage the paint. The Formula 1 is close in performance, but is not petroleum based, and is water washable.
