Anybody know where I can find feed/speed info for milling and drilling
Platinum Iridium? I've checked the Machinery's Handbook 25th ed., and
Machining Data Handbook 2nd ed. (CutData Machinability Data Center). Nada.

I need to mill some ~.050" slots and .030" holes in ~.060" thick x ~.625" x
~.100" Pt/Ir. I don't know the exact alloy. I do know the material is
fairly hard and tends to cook quality HSS drills regardless of spindle
speed.

TIA,
