I say that because I've owned an RF-45 clone mill for about 8 years now and there's no way in hell I could ever take that deep of a cut in steel. Just my opinion based on experiences with my mill.
YMMV

Ed if ya dont mind me askin so how much DOC were ya were you able to take off in mild a steel?
and than something w/ a harder grade ?
yea i think the pm932 is in same class as RF-45 clone no?
all i know is as far as milling /hogging material nuttin to compare with cuz the only mills i have worked on either manual Bridge port basic end mills and Only worked on $2.5 million (Waldrige Coulberg) CNC MILL on Lathe bed . ( helical milling) Used 8" shell cutters filled 50 gal drum in 15 min worth of hogging .
Now on that machine taking a cut all you would hear is dup dup dup dup at the cutter and or smooothe ying ying ying "ying" Stood on a moving platform looking through the glass as ya heard chips flying and the coolant splashing the shield . No problem .2-.4 with %75-80% depth of insert .
Maybe im maybe expecting more than i thought i can do with this mill Btw... I was primarily a lathe hand back in my days
Now as far as the TNMG CNMGs style inserts i have taken .150-.250 cut used to turn down 8-10 Diameter shafts no problem on a lathe with same inserts/ Grades ,cant see why ya cant take ..040
