I would assume a relatively nasty casting which won't take kindly to a weld and too awkward/difficult to braze or hard solder.
I'd give it a super clean, proper squeaky clean ideally vapour blast or shot blast with suitable media. Then I'd fill the outside with a chemical metal and maybe even fill the old broken keyway, machine a new keyway opposite.

Matchless

Squeeze it back to shape, machine down the outside through those ribs, machine up a steel sleeve to go over the outside, tight fit and slightly tapered inside, press the sleeve over the outside with some araldite/locktite/whatever, worth a try maybe, easyish, what is the worst that could happen............ I think that is monkey metal so hard to weld with technoweld etc.

You cannot make honey out of dog ****!
It was a cheap and nasty pulley when it was new,it’s failed due to poor material and design. No amount of turd polishing is going to overcome that
Make or buy a new one

Repair as per 8ob's suggestion plus shrink a collar on to the o/d for a bit extra strength.

Not from any Progress 2 I've seen
Edit: I've never seen a 2 but have seen a 2g, clearly they're very different.
literally hundreds of different types, sizes on the net, stepped pulley... a bit of searching should turn something up. As long as the shaft diameter / keyway is right, and the ratios are roughly right, it'll be close enough, it's only a drill, so a few rpm either way won't change a great deal...
Failing that there's another way if your not bothered about "originality". Put a single taper lock pulley with the corresponding belt width (SPZ?) on the highest speed, align the drive belt and tension to suit. Then drive the motor on a VSD, variable speed drive to suit whatever you speed you need.

Fill the middle up with weld all the way and then bore it out again
This is a welding forum after all...
These are made from ****e or muckite

have you ever actually tried to weld this muck? wouldn't even waste the gas again, it's just garbage.... think its more zinc than anything else, just crap bubbling through, full of impurities, spits and farts, blows out on you.... aye if you're patient, with a lot of cleaning action, and let it boil off, add rod, clean, repeat, you'll maybe eventually get something resembling "welded" however for the time taken, the argon gas / tig rod and electric wasted, you could have bought one for about 15 quid.... hmmm.... know what I'd be doing...

JB Weld?
My tig welding leaves a huge amount to be desired
I could actually glue the damn thing to the shaft. It would fix the wobble - stop giving me bad ideasJB Weld?
