Which bit for router "jointing"?

[Birch]

I seem to be having a short brain circuit here fellas' I want to put a nice edge on some boards before putting them together with pocket screws/glue. Should I use a nice 1/2" solid carbon spiral bit in my table? Or a trim bit with bearing? Seems I used to know this and now I can't remember what I did before?
Does this happen a lot when you pass 65? Or was it 66?

Hi Birch

Just ny 2 cents

I like to use the 1/2" solid carbon spiral bit because of the skew angle on the bit..
it will cut unlike the standard chop angle on the trim bit..

I use the one that Bob and Rick sell.. it's a 1/2 inch flush trim bit and but it also has a shear angle on it.

The one Bob mentions may work as well or even do better than this but I tried this one out with the jointer fence and it worked well.

See....I TOLD ya I knew it. Just couldn't remember. I use the 1/2" shank 1/2" downcut carbide spiral bit. Which makes it an UPcut in my table. Thanks for the memory jog fella's.

The method of use does not change the type of bit cut. An up-cut pulls the debris towards the router and a down-cut pushes it away from the router. Any tear out that will occur will be on the side the debris is pushed towards, in your case the table mounted down-cut will cause tear out (if any) on the top edge of your material.
