You now have a drill bit clamped into the vice dead center of the spindle. Put the shaft into the drill chuck and tighten. Drill out center of the shaft.
The shaft spins, the drill bit remains stationary.
Take care, plan out all the steps, make sure that the shaft can be placed into the chuck without moving the vice and drill bit.
