9mm is the decimal equivalent of .3543. That drill bit should be slightly looser then the 9mm, especially since drill bits tend to drill bigger then that actual size of the bit!
I think it should work, but i can not guarantee it!
I say try it and take pictures for us!!

9mm Barrels have a .347 Bore and a .357 Groove on the Rifling with usually a 1 in 10 twist....

Some useful links to check about Drills and Reamers I have sent the Weaponeer my full collection if he decides to put sections or all of it up for sale there are many good Gunsmithing books included in it

How long is this drill bit ? Due to the wobble, the bore size would come out bigger than 9.00mm, like say 9.1 mm. Also, ideal would be to ream this drilled thingy.
It can still be used by some degree as a "barrel" but with no good fit of the round (not to mention not having rifling), so it would be not even a semi professional metalworking disappointment.
Or maybe it is really for some kind of barrel as the seller says but not 9mm, or you maybe did not measure it very well.
