I'm sticking with the theory the first (initially successful) blade, the HSS, is failing now because it dulled.
The dust is deadly. You could try using a hacksaw with water applied. The water keeps dust from happening, and lets the cuttings move out as they are made.
pcb material can be scribed with a sharp pointy blade like a utility knife or the snap off kind. Then you can follow that line to one side or down the middle of the scribe.
Water cutting usually stops jamming, even with the dull blade.
