just what it says! a cone for centering
Used to ensure the guide bushing is center to the shaft.

Makes sense.

I wouldn't need one of those for a Pat Warner precision base, correct?

Correct, it looks like it comes with it's own version. Seems an expensive way of using a guide bushing? Maybe I'm missing something else it does.

The standard router base and a guide bushing. Most router come with a centering device, and certainly most guide bushing sets do also.
Don't get me wrong, I like buying tools and toys, but that seems a little overkill for the job at hand.
What router do you have, and whats the objective? Maybe we can help save some pennies for you

If the guide bushing is not perfectly centered on the bit, the cut will be closer to one side than the others. That means the way that you hold the router will affect the cut. This matters when you're routing a pattern using a template & you need to get multiple parts identical.

So you can pay for a centering cone & get it right or not & throw away good stock & do it over when the parts come out different.

if you're running the router along a fence and you roll the router base as you do so, then your cut will be wavy if not centered with one of these cones. if you're router is on a track device that rides on the fence - no problemo.

A perfectly centered guide bushing is absolutely critical when using dovetail jigs.
