   Are you talking about a sash set of matched router bits?  I don't understand "stub tennon".  Most tennons on sashes are through tennons, aren't they?

   If you're looking for a sash set, check out:

   You definitely are limited with one of these sash sets to the thickness of material that they say it will handle.  There's no way I know of to stretch it out.  lol.  I've seen other sources in catalogs.  Do a search for "sash set" or the like.

   Last spring I made a series of window sash for a summer cottage using the CMT window sash router bit set.  Take a look at their catalog.  They include an excellent two-page description of how to use the set.  It shows how to combine a dado blade set-up on the table saw with the router bit set to make a longer tenon (about 1 1/2").  Their description doesn't tell you how to produce the overlaping middle rails in double hung windows.  I found that to be the most difficult part of the process but I was finally able to work it out.

   Thanks, I hadn't seen the CMT set--looks like it should do the trick. All the sets I had seen were simply matched or reversible pairs not using the separate rail bit.

   On making double hung windows, there's a great <old> Delta data sheet that describes the making of doors and windows in great detail--it was supplied with every shaper they sold for years--I don't know for sure if it is still available separately, but everybody just starting should have it! :-) It has all these details shown including tooling. Of course, there's a slight rub there as many of the shaper cutters shown are no longer being made or are so uncommon that you may have to wait for a production run to get one (at least in 1/2" spindle sizes) which is where I ran into difficulty. :-(

   No, I don't feel ignored.

   Sorry, I didn't ignore you--I posted a reply thanking you for the link at the same time as the other response I made--don't know what happened that it didn't show up...so, a belated "thanks" for the link

   Anyway, by a "stub tenon" I mean the use of simply the mating rail and stile cutters which leaves only the width of the panel groove as the length of a tenon rather than the traditional full-length tenon.

   I've never seen this is a sash.  In cabinet doors - yes.  But not in sashes.  But anyway, with the CMT bits, as you probably know by now, you could make those tennons any length from "stubs" to full through tennons.

   Good luck with your project.

   Personally, I would prefer HSS cutters to carbide.

   If you use proper feeds and speeds, I feel you get better results from HSS because of the sharper edge you can get on them. Properly maintained HSS cutters are incredibly good tools. I think it's a shame so many people start out with cheap low-end HSS router bits and limited knowledge of tools. They switch to more forgiving carbide to overcome lack of knowledge and experience and never look back. As a result, HSS cutters have become more of a professional specialty item. I even get better results machining tool steel with HSS than carbide--HSS can be some pretty good stuff.
