FWIW - I have a Tormach (1-1/2 HP) - and just got a 2-1/2" Sandvik facemill from EBay. It's overkill for my machine, but I did get it to work pretty well, makes a mess of my shop tho
- throws chips (hot ones) everywhere.
I mill a 2" hunk of steel, .03 DOC at 20 to 25 IPM. I went up to .04 one time and it shut down my spindle, not enough HP. The other thing is the finish is like a cloudy mirror so it's nice.
