The electric drill is one of the most versatile tools. Different drill bits should be used for different materials. By changing bits, you can drill through materials such as plaster, pipes, wood or metal. Protect your valuable drill by changing bits to match the job. Once you’ve determined if you need a chuck key to loosen the bit, loosen and remove the bit. Take care of your power drill and the bits, and you’ll extend the life of your tools.
Below are some steps for your reference
1.Loosen the collet. Hold the collet with one hand and the drill handle with the other. Turn the collet counter-clockwise to loosen it.
2.Remove the bit
3.Set the bit. Hold the drill with your thumb and forefinger so that the smooth part of the drill (shank) is facing the jaws of the chuck. Insert the bit into the chuck and immediately pull it back towards you about a centimeter.
Keep your fingers on the bit and the chuck since the bit isn’t secured and could fall out.
4.Squeeze the trigger.
