Changing the bit in a keyless chuck Dewalt drill only takes a few minutes and does not require any special tools or keys. Instead of a chuck key, a keyless chuck drill has a button on the drill's body that locks and unlocks the chuck so you can open or close it with your hands. Make sure to only use drill bits that are the correct size for the jaws of your drill.

Skill level:

Things you need

  • Dewalt drill
  • Owner's manual (if needed)
  • Drill bit

  1. 1

    Press the spindle lock button to release the chuck. On most Dewalt drills, this is a red button on the side of the drill. Check your owner's manual for the exact location if you can't find it by looking at the drill.

  2. 2

    Turn the chuck counterclockwise with your hands while you continue to press the spindle lock button. Stop turning when the jaws of the chuck have opened wide enough to remove the drill bit.

  3. 3

    Take out the current drill bit, and insert the new one. Make sure to line up the flat sides of the drill bit shaft with the flat sides of the chuck's jaws.

  4. 4

    Press and hold the spindle lock button while turning the chuck clockwise with your hands. Stop when the chuck will not turn any more and the jaws are securely holding the new drill bit in place.

  5. 5

    Hold the drill up, and press the trigger briefly to test the fit of the drill bit. Watch the bit as it spins to make sure it is rotating in a straight line. Let up on the trigger and repeat steps 1 and 2 to reseat the bit if it appears to be wobbling.

Tips and warnings

  • Always wear safety goggles and a face mask when using a Dewalt electric drill.
