How to Change the Drill Head on a Ryobi Drill

How to remove the chuck from a Ryobi drill 

Safety first

1. Always disconnect the tool from power (unplug or remove the battery) before starting any maintenance.

Tools required 

• PH3 screwdriver or Torx screwdriver (depending on drill model) 
• 10–13 mm allen key 
• Rubber mallet (optional, for added leverage) 

Step-by-step instructions 

1. Locate the internal chuck screw 

• Open the chuck fully to reveal the screw in the centre. 

2. Remove the internal screw 

• Insert the PH3 screwdriver into the chuck. 
• Turn clockwise to loosen (note: this is a reverse-threaded screw). 
• Remove the screw and set it aside safely—do not discard. 

3. Loosen the chuck 

• Insert the allen key into the chuck and tighten it in the chuck jaws securely. 
• Apply strong force anti-clockwise to break the chuck free. 
• You may use a rubber mallet to strike the allen key for extra leverage—secure the drill before doing so. 

4. Remove the chuck 

• Once loosened, unscrew the chuck by hand (anti-clockwise) and remove it from the spindle.
