Have you ever run into plywood that messes up carbide?
I just finished a vanity using poplar ply that I bought from a local
hardwood supplier. By the time I finished, my saw blade was tearing and
burning and so were my router bits. I looked at the bits under a magnifier
and they were not only dull, but there were chips in the edges.
I took a diamond stone to a 1/2" straight bit and worked it to a nice edge.
Then I made a few shallow grooves in the plywood. At first, it cut clean
and easy, but soon began to burn again. When I examined the bit it had
chips.
I would sort of expect this with particle board, but not plywood.
I've got about a quarter sheet of it left and I'm thinking maybe I'll just
toss it.

I saw some in a magazine this morning. I'll try to dig 'em up for you.

The glue lines are very hard--you see the result. Depending on the
source, some may be worse than others. I've not used enough sheet goods
since the real swamping of supplies w/ inexpensive imported stuff to
know whether they're using cheaper glues that might be even more
damaging than older G-P and/or Weyerhauser ply or not...anybody??

Really screws up my dust collection system, though.
Are you finding that your Forrest WWII doesn't give you a glue line rip any
more?

ROTFL ... and the latest from OSHA is that the white dust contains calcium
for stronger bones.

Inexpensive, cuts easily, take a nice finish with latex paint. It is the
future of woodworking!

I've used several different types of hardwood plywood, but
the stuff that ate my blades was the "maple" multiply from
the Orange Borg. The glue is hard as rocks and really
dulled an blades used on it. A lot worse than any other
plywood I've ever used. I won't make that mistake again,
even for the price.

It's not the wood as much as it's the glue that eats the edges. Even
carbide cutting edges are subject to wear and tear.
I've found that some carbide tools hold up better than others. You
might want to keep track of which blades/bits do best and which do
worst - and shop accordingly.
I'm still eagerly awaiting (toothed) saws and router bits with
industrial diamond cutting edges. :-)
