Carbide inserts generally take more push and I could see it happening. No violence expected though.

On TLM now, I'd normally expect the tool post to tip forward, digging into the workpiece and stalling the spindle in just a few degrees of its rotation. But with the tapered gibs in it now, its not been a problem since, even with 5x the chip thickness curling away. Darn thing is actually usable as a lathe now.
