If that drill bit is working for you, I propose finding (or drilling out ) a steel collar and fixing it on the bit with red LocTite.
That will hold up to the pressing into the bronze pieces without moving or crushing the way the wrapped tape does.

That just seems a lot easier than machining a new piece.  And since drill bits are readily available, if the punching end ever wears out
so it's not to your liking, it would be easy to make another one from a new bit.  (Heat the bit up with a pipe torch, push the collar off, and mount it on a new bit).

Can't argue that  Max, although the end of the collar will have to be perfectly square to the 2.37 diameter.

If it's really that critical, the collar could be pressed on a drill bit, the the drill chucked in a mill or lathe, and then the face of the collar could be machined so it would be absolutely 90 degrees from the bit.  Then press the collar off, put it on YOUR bit with loctite, and it should be
darn close to perfect. 

The trick there would be to have the collar be a "snug fit", so there would be no wiggle and use a set screw in the collar, so it could be tightened while it gets machined.  A little flat ground into the side of the drill bit with a Dremel would help make the set screw really "bite" so the collar would stay put.

I could machine the face for you if you get that far and like this idea.

Umm... did you forget that you visited my basement, and my horn making shop.  Perhaps you missed the 12 x 36" lathe sitting there.  We can crank something out in a few minutes, depending on the material and how fancy you want it: like some knurling (extra cost!)  Bring over a drawing in IMPERIAL measurements, my fancy Starrett caliper with the easy conversion button has a dead battery, as usual.  Give me a call at your convenience.

@Hornwrecker sorry for the delay in responding.  I did not recall a metal lathe down there, but if the offer still stands, I'll take you up on it within the next two weeks if that's ok. Please PM me with your number, I seem to have misplaced it.
