After purchasing the mystery end mills from McMaster Carr for steel, I saw that online carbide.com was back in the warehouse shipping so I decided to pick up some 3 flute aluminum end mills. I am really happy with these.

Tried the 1/2” out on the new mill. Took a side cut about 3-4” deep at .040 doc with the cutter moving at a fast pace with the power feed. Smooth as silk.
