Gunner, I ordered right from K&M. Basically you'll need an expander mandrel, hand cutter with 284 stud/cutter and an adapter that I can spin the case with my cordless drill.
Here's the stud that goes into the hand tool. You can see the cutters on the end.

Give them a call though. They will get you set up right. Good folks to deal with.
