Installation Info
Most chucks will have a reverse threaded screw locking them in place that will have to be removed before unscrewing and replacing the chuck.

To seat the chuck firmly on the spindle, run the drill in reverse at low speed for a second after hand-tightening.
If you notice slip on tough materials, retighten at mid-stroke: stop, add a quarter-turn by hand, then continue drilling.
