Prepare Your DEWALT Drill for Fixing
- Ensure the drill is turned off and disconnect the battery to prevent accidental startup.

- If applicable, remove the battery from the drill for safety.
Apply Penetrating Oil and Loosen the Chuck
- Spray penetrating oil (like WD-40) into the chuck’s threads and around the base.
- Allow the oil to sit for 5-10 minutes to loosen rust or debris.
- Use an adjustable wrench or a chuck key to turn the chuck counterclockwise, attempting to loosen it.
Manual Removal or Replacement
If the chuck does not loosen after applying oil, consider using a rubber strap wrench for extra grip. If the chuck is damaged or stuck beyond repair, replacing it may be necessary. Refer to your drill’s manual for specific removal instructions or visit an authorized service center.
