Indeed WD-40 seems to work well for Al. I have some Al that is plain
touchy. Creates heat very quickly and then I get adhesion. 6061-T6 seems
to be OK.

cutter as it runs with neat cutting oil. If I'm surfacing a plate or
machining
around a big block, I put a few drops of cutting fluid on it and then
smear it
with a 1.5 inch paint brush.
I think I have said this before, but, Castrol Ilocut 154 (think mine was
called 64 when I bought a 20 litre drum 25 years ago and still using it
daily)
is a neat cutting oil that is fantastic.
If I skim 2 bits of aly, one dry and one with oil, I can easily see the
difference. Drip oil with deep pockets and then remove the swarf with
compressed air. Running the mister all the time makes every thing sticky.
I never mill aly without fluid. Aly friction welds to easily.
Aliexpress, 20 syringes with needles for a couple of $$
I now have syringes next to the drill press, mill and lathe.
I still use flood with steel if I have to remove heat.
Flood if you have a fully closed in machine.
Still use HSS for plastics. Seems to cut the best.
Cheers Wallace.
