Domino tenon cutters to make your own tenons.

Embossed.

Are you sure?  A few years ago I asked one of the Festool experts here, and he told me the flat sides were embossed with the Festool name, tenon size, and pockets for the glue, but the ridges on the edges were milled.

Sorry. I missed the ridges part of the question. I took a look at the dominoes and saw the embossed marks.

Finally a router bit designed to make tenon sticks! Shouldn’t have taken to so long but this one does it and has a clever twist Buy them at TSO.

Just noticed that Woodpeckers produces tenon bits in both metric and inch sizes. I'd imagine these would give a real smooth cut.

But more than that, Woodpeckers have expanded their router bit offerings substantially.

Here are just a few that are of interest. Finger groove, micro round over/pocketing, phenolic with chip breaker, small diameter compression/pattern & spoil board with carbide inserts.

The difference in our tenon bits is that we decidedly are NOT trying to replace ready-made Dominos, but rather to make tenons that can be used for exposed joinery. Hence, smooth radii with no ridges. That said, I've used them to make over-sized tenons for double and triple width Domino-cut mortises. I sliced a couple grooves along the sides with a a carving vee gouge and was careful with my glue application, and it was all good.

I have made my own, years ago, before it was a ready-made thing. I did the 6mm with a regular 1/4" round over, but it takes four passes to complete. I later went to a half-round, to make it easier, but it only works with that one size. I'll probably go with the Woodpeckers one, for 8mm and maybe even 10mm.
I've had a little bit of experience with their bits. They have been great. I even used one of the bowl bottom cutting bits, even though the Shaper people tell you not to use bearing guided bits. Personally, I don't see the issue, since I'm not cutting past the depth of the flutes anyway. Besides, you could always take it off.

As a side note, the bits that are intended for Phenolic material work great on Corian (and other brands)
It's not "officially" sanctioned, but I have tested it quite a bit. As long as your fence, rail, whatever you use to cut straight, is actually straight, you can get glue-seam-ready edges with one of them.

I have used the 1/4" spiral flush-trim bits too. They are really good too. My next purchase is going to be the 3 flute version.
