Are These Lugs Swaged To The Drum?

3/8, or 7/16 drill thru the head of the stud, wallow the hole a bit, the head will fall off, then the stud will pop out the front with a punch.
Easy-peasy .
Yeah I get that. I don’t want to destroy the lug or remove it from the hub. I only want to separate the drum from the hub while leaving the studs intact.
