Does someone have torque graphs for the spindle in question?
mfg specification is "up to 40Nm" if I found the correct one but does not really tell what speed range you have with that torque.
REIME NORIS | Torque Calculation
Reime-Noris tapping torque calculator gives 20Nm torque for dull tap so it doesn't look like lack of torque.
Bastard extra coarse tap is of course weaker than anything else but the F size drill is only 50% thread soooo it shouldn't be too bad?
