Repairing metal housing.
What material bit for either 1/4" OR 1/8" shank hand drill motor or Dremel is best to use ?
I have many of these to do.
For steel, silicon carbide. Alox is much slower, and silicon dioxide best used on hard cheese rinds only. Diamond tends to be very variable. Tungsten carbide is good stuff.

How do the vitrious silicon carbide bits hold up ?

I'd use the Dremel CBN (Cubic Boron Nitride) wheels. I bought a few to test them and they are great for jobs with steel.
Can you just re-cut the end? Maybe a step drill bit, or a conical bit. (A dremel sounds a bit wimpy for the job, unless it's thin walled SS.)

I may not understand exactly what you mean. When plumbers and electrician cut pipe or conduit they use a conical pipe reamer or for lighter pipe a flat vee shaped one. CP
Did anyone mention a tapered reamer ? The pipe threading machines usually have them built in.

Do they work on rigid? pipe?
