I do a ton of work with small cutters and in aluminum, I use a coolant mister
with alcohol, I use as much air as possible and just enough alcohol to keep the
part wet. The parts feel like they were in the freezer when I am done.
As Jon said keep the work cold.

Tom,
Wow! what a nice write up.
I use a mix of sodium nitrite and physan 20 in my water. I noticed your
water is green, what are you using? How does cutting submerged work?
I've been wanting to modify my water table to do this for some time...

These are long reach 2 flute, they do flex a bit. I suppose I could be

danger! the coated tools are terrible on aluminum. the coating has a micro
roughness that nucleates chip welding of soft aluminum. coatings are good for
lubricity of hard material chips against the cutter, but a mirror smooth
surface is best for carbide in aluminum.

far
