I think this is what I am looking for if I replace the pilot bit with an 1/8" smooth steel rod. Note the set screw in the picture. And the flat one is on sale!!!

I am looking to follow the through hole when I am drilling the tail weight hole. The other step drills I have seen are one piece but this one looks like it will do the trick.

Thanks Pete!

That looks like what I used to drill out spot welds when I was doing autobody work.
Check the countersink drill bits out at Lowes or Home depot; they secure the cutter to the drill bit (allen set screw) and you could put a rod in place of the drill bit.

those look like they are made to drill pocket holes for screws. Like a Kreg type pocket hole drilling machine type thing(although the Kreg system uses a step bit)

I used to use one in a shop for assembling face frames, now I use something a bit different.

I bet you could find them as replacement bits for the boring machine that is meant to drill the pocket holes, there are many varieties, makes and models.

I see you found it and the one you need is on sale, nevermind.
