Changing Bits on a Keyless Drill:
The chuck loosen:
The chuck is a piece on the drill’s end which loosens and tightens to hold the bit. Grasp the chuck with one hand while holding the drill handle with the other. Twist the loosening chuck counterclockwise. Another choice is to gently pull out the trigger while holding the chuck.
Loosening the chuck will open the jaws that clamp onto the drill bit.
Take off that bit:
The drill bit you currently have in the drill should start wobbling after you loosen the chuck. Once the jaws that lock it to the drill are loose you should be able to pull it out of the drill quickly.
Place the bit aside:
Keep the bit with your thumb and index finger so the smooth part of the bit (the shank) meets the chuck’s jaws. Keep your fingers on the bit and the chuck, because the bit is not protected and may fall out.
Squeeze out this button:
Give the trigger a few short squeezes to lock the bit into place. Your other hand should still keep the bit loosely in place while you’re doing this.
Trigger the mechanism of ratcheting, if appropriate:
If your drill has a ratcheting mechanism for adding extra pressure to a drill bit’s shank, you’ll have to click it in place.
