Put a piece of carbide (a 7/32" drill bit works great) Thanks,

I do it that way, but a bit may not be a good choice since it's sharp. A brass rod from the local hardware store would be good.
Cutting them is best if you can. Fool around with some bad one's and see what else works. Heats good just wet a paper towel and stick it to the shaft to keep it from heating up and you won't hurt the bond of the carbon.
