Hey,
if it's glass fiber reinforced plastic, or you're cutting PCBs with
it, you'll need solid carbide blades in order to be able to expect a
meaningful tool life. Even better, if this happens regularly or in any
kind of volume, you'll be probably better off buying a cheap small CNC
router like a 2030 or 3040 that takes dirt cheap 1/8" carbide endmills
and router bits (corn cutters). You can set up a fixture for holding
multiple connectors on the table and be done with dozens of them at a
time.

Thank you Peeter, Michael, John.
I'm currently leaning on thinking I had a couple degrees angle of "attack" error/tilt I didn't realize the saw squaring device creeped to have. The mirco-table saw is great overall, but doesn't have extremely precise adjustments of the geometry of cutting. Not 100% sure that's what was causing my conundrum, but the working theory I'm on right now.
I am confused about John's point. What dust is deadly? PCB sawing dust? If yes, I'm not cutting PCB in this particular step under examination here - but rather plastic (fiberglass?...) from the edge connector body - though I've occasionally cut PCB and wasn't aware there's an ominous aspect to it. John - would you care to elaborate?

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.
