I have used a Sears Craftsman hole saw and a 3/8 inch electric drill at slow speed with a lot of oil. The same hole saw has done a dozen drums with each drum taking about fifteen minutes. The studs often just fall out on their own when the shoulder is cut away with no damage to the drum. I'm sure the expensive cutter works faster, but for occasional use, the hole saw is the way to go.
