The Unibit works great. If you stop at the right step on the bit, you can thread the nipple right into the drum. ( I still tack weld it on the inside)
Not sure why you think a hole saw is a pita. Punch where you want to drill. Use a 1" hole saw made for metal a drill your hole. Bam a 3/4" pipe will screw right in no problem. Takes maybe 10 seconds to drill a hole.
