Spindle will continue to turn a while after, for a smooth stop which
probably is required to not break gear box if machine have that angle
must be known beforehand and control loop tuned so there is no overshoot.

Overshoot caused by inertia of the motor and other rotating parts. Without a
brake that *stops right now* one must account for the tap to keep turning a bit
after the spindle is commanded to stop. If the mechanical and electrical can
withstand it, the motor can be reversed at just the right time to reduce and
control overshoot. The tap will still continue going in a bit before
electricity overcomes mechanical inertia to reverse.

Sorry, may be too new to this or just not getting your use case, but I
don't understand why properly measured/probed tools end with excalibured
taps 🤔
