Why didn't I ever notice this before? I was rabbeting out
a cabinet back and getting these nasty little tearouts, the
result of:
1. the cross grain underneath the microthin layer of hardwood
veneer having sway and tearing right through, so next time
I will try
2. A sharper router bit.
If there's a way they can make that top layer thinner, they
will do it.
While I agree with the recommendations to score the wood before routing it,
you might also try a sharp downward-cutting spiral router bit.

You can also use a utility knife to score the top veneer layer to help
eliminate tear out.

I was thinking the same thing, but using a downcut bit I think it would be a
good idea to do a pre-cut with a smaller diameter straight or up-spiral to
hog out most of the material, because the downcut spiral isn't going to be
self-clearing if you're not doing a through-cut.

Score it properly with a good straight edge and a sharp razor knife and you
can eliminate those tear outs completely.

Umm, down cut or not, a rabbet cut will not capture the waste as a dado
will. There will be no problem with build up using a down spiral.
