What did I buy? B&S9-JT3

[Ultradog MN]

I have been watching for tooling to fit my old Midway Millmaster mill which uses B&S 9 collets.
Found this NOS B&S9 to JT 3 adapter online and bought it. I have a spare drill chuck with JT3 and want to use them as a pair.
It arrived today and it seems fit my spindle and it does fit the chuck but it has a tang on it instead of a tapped hole for the drawbar.
Now what?
Can I use it as is or do I need to cut the tang off of it and drill and tap a hole for the drawbar?
Am new to all this so bear with me.
Thanks

the tang can be certainly be removed with an angle grinder, then drilled and tapped for the drawbar

Yes, I could cut the tang off and drill/tap it.
Question is do I need to?
Chucking it up to do it might be a bit tricky with both ends being tapered.

You could mount the chuck on it, then put a piece of drill rod or other precision round in the chuck, then hold everything with that.

Thanks to you also. I thought of that too.
But maybe I should rephrase my original post.
My question is:
Can this be used in the mill without the drawbar or is it imperative that it be used with a drawbar?

I would say yes, but only if there is a place on your quill for a drift to remove it. My guess is that there is not because you have a drawbar. I think that you will be better off with a drawbar anyway.

You found out the hard way that there are two different styles of B&S #9 arbors. Drill presses often don't use drawbars but milling machines do, since you often need to change tools.
I think you would be better off returning that arbor and get one that's tapped for a drawbar
Trying to machine that one by holding a shaft in the chuck will probably prove unsatisfactory in terms of runout

for drilling, you may be ok without drawbar retention

Until it gets really stuck in there.. maybe could make a dedicated whacking bar out of aluminum instead of mushrooming the end of the drawbar

It would depend on what your spindle has inside, I had a #2 B&S that had a non accessable tang slot; you just slapped the chuck in and used a knockout bar to remove it, same with tanged milling arbors and end mill adaptors.
