rbent is right-- I never drill stainless with a 118 bit: save those for mild steel or alum.: too much down pressure to go anywhere in that size range for a 118---- hard to feel the cut. Operators have to develop the "feel" for cutting.

Milling hard surfacing would be horrible. There's quite a difference between a flat even surface that is of 65rc, and a surface that is bumpy, uneven, warped? and the hardness is probably not perfectly even. Much different grain structure also. It would be hell on the cutters. Unless you grind most of it and face mill it for the final touch.

In the shop you may apply further treatments to different sections, but the "mill hardening" would refer to the as-delivered material. If you bought mild steel and then forged and treated it yourself you would call it age hardened. If you bought engineered steel with controlled properties it would be received as "mill hardened" to that spec.
