How can I change the drill bit on a Dewalt drill?
To change the drill bit on a Dewalt drill, first make sure the drill is turned off and unplugged. Then, locate the chuck key that came with the drill. Insert the chuck key into the chuck and turn it counterclockwise to loosen the jaws. Remove the old drill bit and insert the new one, making sure it is securely in place. Finally, tighten the chuck by turning the chuck key clockwise.
