Knowing that this broken pin is in a blind hole, I tried with some crappy punch/cold chisel. Only to find that the punch/chisel got damaged first.
Thanks, would appreciate if you could point me to some better punch?

First, if you can, post a pic of item in question, This might help us in determining what the real issue is. Second if you have the owner manual, check to make sure it is a "roll pin". Im sure it is , but......
If you dont have the manual Google Delta and they have manuals online with schematics.
Second, I would not recommend heating/torching any metal as this might take the temper out of the all the metal, this will weaken the metal.
Lastly, like everything in life, size and technique are the key to success.
Take some metal penetrating spray and spray the area inside and let it soak in for a day.
Next, any hardened steel punch pin should work. Maybe think about investing in a set as I have since we all have TS, BS, etc.. that need maintenance, etc....... Enco.com other than HF is a place to check out metal working tools.
Take the size most closely matching the blind hole and then start tapping (feel if it is giving way) if so, then bang harder till it pops out.
If it doesnt feel like their is any movement, it may be angled (stuck) in the blind hole, in which case take a smaller punch and hammer 3 to 4 sides at a time to see if you can straighten out. once straigthened, then take the larger punch and hit square and straight to pop out.
Now this does take some time and patience if it is stuck, and dont think its not working if it doesnt pop out immediately, it will....
Try this and let us know how you fare. In the meanwhile I will check my bag of tricks for another approach.
