When should I thread, when should I use a die?

Ok, I'll bite. It looks like a chuck, but the jaws are threaded, so it must be an adjustable die of some sort.

What's it commonly used for, and what's its proper name? )

It is a Geometric threader, there is also a rubometric in the box.

Very cool. So it does a set pitch and TPI over a wide range of diameters. Obviously a tool best for production work as it doesn't look cheap.

What's the difference between the geometric and the rubometric?

Thanks,

My guess is it is like a powered pipe threader in which the jaws adjust for various diameters but all have the same thread pitch.

Sorry folks I don't really want to change this thread into a geometric thread so I started another. http://www.hobby-machinist.com/showthread.php/8419-Geometric-threaders?p=70674#post70674 I'll try to answer in it if needed.

Just another accurate way to thread to shoulder. Pricey but quick, and repeatable.
