Trochoidal milling!
Lets you do 5mm passes in one go with a 1/8. 
No cooling needed either.
I have a 1/4 two flute for aluminium as well. 
That’s pretty cool. I don’t think my CAM software will do anything like that. I’m using KIRI:Moto
Hmm, I just googled it. Fusion and EstlCAM have it at least. Since Estlcam is free as an unlimited trial, you might as well give it a shot, at least for aluminium.

I generally use the single flute 1/8” from Ryan…
And definitely use Trochoidal milling. I run full DOC for the material. I also use a mist coolan of IPA and it does keep it nice and cool. But it isn’t a total have to. I’ve done it without as well but I find it leaves a better finish with it.
What clamp is that?
Might have been those: CNC Clamp by Holy1 - Thingiverse
It’s been a while though. My new table does not have those inserts as hold-downs.
Yes, my apologies for using an abbreviation, Isopropyl Alcohol.
@Jonathjon is the success story I watch for cutting aluminum (and other stuff), he was one of the people I was hoping was going to chim in.
@Tokoloshe is a big advocate of Trichoidal milling, and as you can see Johnathan also uses it. I didn’t think about mentioning that until after I posted.
So the people I watch for that knowledge have offered up the info I was hoping you would get from experienced users. Instead of me, that understood the theory.
This might be of interest to you as well.

My own 3d printed ones. Made them similar to a metal version I saw.
I keep meaning to clean up the stl and post them on thingiverse.
I based my design off these Slab Clamp Dogs
I will be looking into how to do that. Kiri:Moto does not have that option that I’m seeing
Is there a reason you don’t want to use Estlcam?
What kind of setup are you using to control the mist? and would denatured alcohol work or does it need to be IPA? I assume its the evaporation that is providing the cooling effect so i’m thinking any alcohol would work
I mainly use a Mac and it didn’t appear to be compatible when i looked into it.
He asked about mine, so the link was correct.

I use [this](Mist Coolant Lubrication Spray… Amazon.com) mounted to @DougJoseph kenematic mount
I don’t see why the denatured alcohol wouldn’t work but I’m not really sure
is there a good tutorial on how to use ESTLCAM. I’m not at my machine right now but was gonna try to setup toolpaths and it just does not seem very user friendly. I’m sure its a error on my part its just very frustrating.
He has some youtube videos for an older version that are real close to version 11
He also has a ton of videos for 12 (in German, though).

Denatured may have methanol in it ( at least the brand I buy does), I’m not a doctor but I would wonder about breathing in methanol fumes. So that is something to consider.
Some links and pictures here…
