How to attach a Drill Bit to a Drill or Impact Driver?

If using an 18V ONE+ Drill Driver/Hammer drill

1. Ensure safety first 

• Disconnect the battery pack before inserting or removing any drill or driver bit.
   

2. Identify the keyless chuck 

• Ryobi 18V ONE+ drills feature a keyless chuck, which allows for quick and easy bit changes without tools.
   

3. Open the chuck 

• Hold the drill body securely with one hand. 
• With your other hand, rotate the keyless chuck anti-clockwise (to the left) to open the jaws wide enough to insert the bit.
   

4. Insert the drill bit 

• Insert the drill bit into the centre of the chuck, ensuring the cutting or driving end is pointing out of the drill. 
• Ensure it is straight and centred, and at least 20mm into the chuck.
   

5. Tighten the chuck 

• While still holding the drill body, rotate the chuck clockwise (to the right) to tighten the jaws around the bit. 
• Make sure the bit is securely gripped and does not wobble. 
• Do not over-tighten the chuck.
   

6. Test the bit 

• Reconnect the battery pack. 
• Grip the drill by the handle, ensuring your other hand is clear of the drill bit. 
• Gently squeeze the trigger to ensure the bit spins correctly.

If using an Impact Driver

1. Ensure safety first 

• Disconnect the battery pack before inserting or removing any drill or driver bit.
   

2. Locate the chuck 

• An impact driver uses a ¼" (6.35 mm) quick-release hex chuck. 
• This chuck is designed for hex-shank bits only. 
• Ensure the drill bit has a ¼" (6.35 mm) hex shank.
   

3. Insert the new drill bit 

• Pull the chuck collar forward (away from the tool). 
• Insert the new hex-shank bit into the chuck. 
• Release the collar to lock the bit in place.
   

4. Confirm the bit is secure 

• Gently tug on the bit to ensure it’s locked in and won’t fall out. 
• If it pulls free, repeat the insertion process.
   

5. Reconnect the battery 

• Reconnect the battery pack. 
• Grip the drill by the handle, ensuring your other hand is clear of the drill bit. 
• Gently squeeze the trigger to ensure the bit spins correctly.
