Slot, Drill, Thread -- Correct Order

[DroopyPawn]

I need to cut this piece.

There's a slot going to the larger hole and a threaded hole that runs through the slot. My question is, what's the right order to cut the slot and drill/tap the screw hole?

Do I cut the slot and then drill and tap the small hole? Or do I drill and tap the small hole and then cut the slot?

save the slot for last , unless your working within tight tolerances , it depends a lot upon the material your using ,once you cut the slot the part may spring which will throw out the larger hole dia and the flatness

Yes to dertsap's advice.
