I really like my 2" SEHT facemill. I use the ground alu inserts, even in steel, as my mill isn't beefy enough to push the molded steel inserts properly. It does very well up to ~0.03" DOC in steel and pretty much whatever in alu. Funny fact, after I tried it out in alu for the first time I built all the chip guards for my mill. Sounds like a platoon of machine guns rattling off the guards at full chat
