Proxxon makes circular saw blades entirely out of tungsten carbide. Those
should hold up reasonably well.
I've tried one and the cut is perfectly smooth and straight, but the dust
and terrible noise prevent me from using this method.
I've even looked at drilling under water to avoid the vacuum noise and dust.
It seems to work very well, but the water makes it too difficult to aim the
drill exactly. With a CNC setup, that may be a workable option to both drill
and cut the boards.
