drilling out lugs from hub, disc brake upgrade

I still cant finger out why rear axle studs keep getting mixed into this thread.
Those studs weren't swedged into a hub assembly, can be smacked out with a hammer, just damn different.
This is correct, but the studs should never be forced out the wheel-face side of the hub flange, the swaged splines are there to retain the front drums....no other reason. If one is
to be dainty about it, & is restoring the OE assy., needing to replace one or more damaged studs,..& can't bear the slightest scratch on either hub or drum face.....sure drill away.
But if You just need the studs & drum gone, I'd burn thru' all 5 of those studs in 2 minutes & knock the ***** apart w/a wafer wheel, there will be no more swage left to worry about.
