Name that tool

Which one is the mandrel and which one is the arbor?

 

[Jeff.64]

The mandrel holds the work (gear) and the arbor holds the cutter.
Now do fixture vs jig

Edit:
drill vs drill bit
and bolt vs screw.
I just couldn't help myself.

Involute gear tooth cutter or the workpiece (unknown)?

See what Jeff64 said he is right. And thanks for commenting. This really could be fun if others would chime in with their tools.

Under normal conditions you are right Jeff64 but neither is the mandrel. What appears to be a mandrel with a gear on it is actually a shaft that has a gear made into it. This is why I am repairing the gear instead of making just the gear or buying just the gear.

Okay, we have an arbor and a shaft. Where is the mandrel?

The one that is not the arbor or the shaft.

They are kind of interchangeable

I don’t understand your statement that “what appears to be a mandrel with gear on it is actually a shaft that has a gear made into it”.

Why would both the shaft and gear need keyways if the gear is made into the shaft?
