Drill Bits slip in RYOBI Drill Driver chuck

1. Clean the drill bit

• Dust or liquid on the shank of the drill bit can cause slippage. 
• Wipe the end of the bit (the part that goes into the chuck) clean before use. 

2. Inspect and clean the chuck

• Chuck jaws may be dirty or obstructed. Clean them using a small pipe cleaner brush or similar tool. 
• Ensure the bit is seated evenly in the chuck jaws before tightening. 
• Apply equal pressure when tightening to ensure a secure grip. 

3. Check for wear and compatibility

• Inspect drill bits for signs of wear or damage, which can reduce grip strength. 
• Verify the chuck’s capacity rating—this is usually engraved on the chuck or listed in the instruction manual. 
• Using bits outside the chuck’s rated capacity may result in poor performance or slippage. 

4. Consider bit type

• Bits with a hex shank or 3-flat shank offer better grip and reduce slippage. 

5. Use the right tool for small bits

• Smaller bits (1–3 mm or less) may not grip well in standard chucks. 
• For precision tasks or small holes, consider using the Ryobi 18V ONE+ rotary tool, which is better suited for intricate work. 

6. Alternative tools for oversized bits

• If your bit exceeds the chuck’s rated capacity, consider using a drill press or rotary tool for better control and safety.
