Is a router centering bit used to center the bushing guide exactly in the center of the router base? Is this done by chucking the centering bit into the router, then positioning the bushing guide of the tapered point of the centering bit and then tightening the knurled ring onto the bushing guide?
And incidentally, a saw drill bit came with a set of titanium drill bits I recently purchased. What is a saw drill bit used for?

Larry,
The bushing centering bit that I have is a cone that you chuck into the collet and lower the router until it touches the bushing and then you tighten the bushing collar holding the bushing against the bit.
A saw drill bit allows you to drill a hole then apply lateral pressure on the bit to saw a slot kind of like a rotozip concept, except it does not work real well. I usually use tools that were designed to do their job not three others, but in a pinch it will work very slowly and a very rough finish.
Thanks very much for the guidance.
I've used router centering pins to locate the bit dead center in the hole in the baseplate. If it's off a little, you can loosen the screws holding the baseplate in place and make the adjustment. This is important if you are using a template guide to get the bit centered so that there isn't any slop created by having one side of the bit closer to the guide than the other. Hope this helps.
Jim
