Are These Lugs Swaged To The Drum?

I borrowed a swedge cutter from an old guy I knew at the dealership in town. It was basically a thick hole saw that kind of looked like an deep well impact socket with teeth. Goodson still makes them. Ouch!

I was told NOT to try and beat or press them apart, but that was 20 years ago. Good luck!
