This is a old thread, but I'll bump it up.
Inconel really doesn't like high SFM.
I successfully drilled 200 .032" holes at about .2" depth. Walter cobalt drills.
400 - 500 rpm, 0.1 IPM feedrate, 0.05 peck.
You want about a 0.0001 to 0.0002" chip load. Drills are effectively a single cutting edge, not two.
