Hi all, After lots of trial and error along with some great advice from this forum, I finally feel like i’m getting the hang of cutting aluminum with my pro xl. One thing i’ve found that makes all the difference is using single flute endmills. Most of the time i can get away with using 1/4’ and 1/8’ cutters but often i need to do some detail work with a 1/16. i’ve been using the #112 I purchased with my machine and while they do work, I find they have a tendency to get a little clogged up with aluminum chips. I know C3D doesn’t sell smaller single flute cutters but I was wondering if anyone might know of a source for some?
If you need really small single flutes, Datron is my go to. They are a bit spendy when compared to others but their quality is excellent. Here is a link to their single flute page:
1.6mm is roughly equivalent to 1/16th.
Another option is Amana. They are not as expensive as Datron but still more money than generic tools. Here is a link to their uncoated single flutes for aluminum:
If you are looking for better surface finishes Datron makes a line of balanced single flutes called their “4 in 1” series. They are fantastic but expensive. The balancing really helps when you start using larger tools.

If you’re ok with the 1/8" shank.
Amana 51470 is what I’ve used with success.

Not quite 1/16", but we do have a 2mm option:
which I’ve been using a lot where I need small detailing.
I appreciate all the suggestions, now I have some research to do
