Okay, I know... "It's magic". 
First, let me make sure I understand how this gizmo works. You put the tapmagic in your drill press (mill) and then connect an arm to a stationary thing off to the side. Then you put the tap in the bottom. You position the hole and start the drill press turning. When the tap engages the hole you take your hands away. When the force gets to be too much, or the distance has been tapped, the thing MAGICALLY starts rotating in the opposite direction.
Okay, I can understand friction clutches. But it's that "goes backwards" part that has me confuzzled. I've tried finding a good explanation with diagrams or pictures of a disassembly, but I have not found one. Anybody know of a pointer to one?
