It would work for a tendon too. With a standard boring bar you would cut on the back side or upside down with the lathe in reverse.

I will be following this thread to see how well this unit performs. It could be just the ticket for those final cuts on transparent type acrylics to reduce tool marks before painting the inside of the blanks.
I know using a boring head in a milling machine was the cat's pajamas to get precise fits but then again that was using an automatic feed and a much more solid set-up.

I can see how it might be useful for that. I don't do tenons all that often, but now I might just give it a go.
A reamer will also work for getting a smooth hole in the blank. Just used one on a semi transparent blank, it left a smooth "clear" finish to the inside. Not polished but smooth.

I use a reamer on my Sierra kits and get similar results. Just may get a couple for other pens I make more of like cigars.
You could grind a flat spot on a round bar (12mm) and attach a square carbide cutter. It would cut on both sides for holes and tendons.

That's exactly what I'm thinking of doing

It can cut a tenon if you can reverse the direction of your lathe. Another option is to order a shaft and cutter with a diameter that matches the size of your holder, mine was 1/2 inch, then cut the shaft down to 3 inches in length. The you can cut with the lathe turning normally. The only issue is that you can not cut both tenon and holes with the same cutter, if you are using it to make kit less pens, it is to wide for most holes. You will be better off using a drill bit to match the size needed for the tap you are going to use.
