I am looking for an end mill for aluminum (preferably 2 flute) with a .040-080" corner radius. I need it to cut at least 2.375" deep but multiple passes with a necked down end mill is fine. The diameter would be 3/4"-1", ideally 3/4" as I don't want to break the bank. Carbide is OK as long as the price is not too crazy.

I think Helical makes such a part. HMG-RN-033-20750-R.060 is a 3/4", 2-flute, 0.060" corner radius, reduced neck (1" LOC, 2.5" reach).

Helical's online catalog doesn't suck. Have to go through a distributor to get them, but they added a feature recently where you can shop on their site and have the BOM sent to a local distributor, who will get back to you quickly-ish.

I really like their stuff overall. I have a few complaints about their product lineup and I really wish I could order direct but overall pretty happy.
 
YG 67904 3FL Hss .060 corner rad 3" length of cut.

YG 80901 3FL Hss .060 corner rad 2.250" LOC

YG EA40482 3FL Carb .060 corner Necked 1" LOC 3.250 under neck

Helical 81527 (h40alv-rn-a-30750-r.060) 3FL Carb .060 Corner rad 1" loc 2.5 under neck

I've got two of these 1" Kennametals, new, with .06" CR. Says 2.25 LOC, measures at 2.375" or within thousandths of it.

If that works for you, $125ea. shipped USPS flat rate. Can go out tomorrow with Paypal today.
