I was using 50-1250 range.. where torque is higher due to higher mechanical reduction. It is pretty easy to stop it by hand...
The issue is in control board, the motor speed is determined by voltage (generated by PWM from processor) and there is no feedback.
You are welcome to have a look yourself - PM me so we can arrange something.
Cheers,
Bojan

The reason I ask is that I was considering exactly the scenario you mentioned: cutting some larger threads. I suppose one could be gentle with the depth of cut and use brass or Aluminium rather than steel to try and accommodate any issues. I'd be interested in your thoughts on the issue as you've observed it directly and stopped it with your own hands, how hard I don't know.
