Anyway, I was responding to the OP question about getting a down cut spiral bit with top bearing
I don't think you can get a bit like that(flush cut that is)

Sometimes it is helpful to also answer the question that was not asked, which relates to alternative ways to get the job done, as well as what exactly the job is and what is the function and size of the hole in this particular case.
So those questions of:
A)
B)
...often also have
C) None of the above
or
D) All the above.
It's a sewing machine table. The sewing machine will drop in the 5"x15" hole and it's bed will flush with the 30"x30" table top which will give a larger, flat area for large fabrics like quilt tops. It has to fit tightly so fabric will not get caught in the crack. I just spent some time testing with scrap lumber and a rough plywood curved template on the router table. I think I can get the bit I already own – 1/2" flush bit with bottom bearing which cuts a depth of 1 1/4" to work. I'll first cut out the center, about 1/8" from my final line with the jigsaw, and then follow the sewing machine shaped template with the bearing bit. I'll need 1/2" radiuses on the front 2 corners and then 1/8" back 2 corners. I'll probably just file those 2 later to be sharper corners.
[member=13226]Iwood75[/member] I just completed a sewing table for my wife for Christmas and had to cut a hole in the plywood to allow an acrylic insert that matches her sewing machine to sit in the top. My hole was 12.5" by 21". I cut it with the TS55 and a track as far as I could, then used my jig saw to finish the cuts. This was then the pad the sewing machine sat on the air lift mechanism I bought from Rockler.
To dado the cut, I used a bit I bought from Sommerfeld that had interchangeable bearings. I needed a quarter inch opening, so put the appropriate bearing on the bottom of the bit and used my OF1400 to cut the dados. I had to chisel the corners to make them square, but everything came out perfect for me.
Good luck on whatever method you use. Bill

Are you sure you need to go all the way through in one form or will you need a shoulder for the machine flange to sit on? I don't know myself but it seems like you will need something to keep the machine from falling right thru. Might be a dumb question for which you have already have the answer but I feel compelled to ask.
