Newer Black & Decker drills are equipped with a keyless chuck. This handy feature allows for rapid drill bit changes. The keyless chuck system operates on a process that automatically locks the spindle when the drill is turned off. This allows you to tighten or loosen the chuck with one hand while holding the drill in your other hand.
Release the trigger and wait for the drill to come to a complete stop. Unplug the drill.
Hold the drill firmly and grasp the outer sleeve of the drill chuck with your free hand. Rotate the sleeve counterclockwise to loosen the chuck.
Remove the drill bit and set it aside. Insert the new bit into the chuck. Make sure the cutting end of the bit is facing up.
