Electric Drill Bit Slippage
I have a Craftsman 19.2 volt drill with a half inch chuck. Many times,
especially while pressing hard into the material being drilled, the bit slips. No matter how much I tighten the chuck, the bit continues to slip. Other than replacing the chuck, which isn't worth it, what can be done? Is there a spray of some sort or something else to provide a better grip on the bit. |

Know whjat you mean especially 'getting older' keyless chucks! Grind a couple of flats onto the drill bit/s. For hard drilling anyway. Some are probably already scarred from the slippage? |

Maybe dull bits are your problem. |

Electric Drill Bit Slippage
You can grind 3 flats on the drill bits which if not done exactly
symetrical will make the drill bit wobble. Aside from tightening the chuck with a key, it's the chuck thats letting you down and would need to be replaced. Sears may give you a new drill if you explain the problem, I think they have fairly good customer service. |

I bet that it is a ****ty keyless chuck, in which case the fix is to replace it with a decent Jacobs keyed chuck. nate |

I'm not sure what the OP's problem is, but the keyless chucks on my DeWalt cordless drills have never given me a problem. |

Try using a little cutting oil Use sharp bits, If you are drilling a large hole drill a small pilot hole first. Still having problems, you have a bad chuck. |

Is there a spray of some sort or something else to provide a better grip on the bit. At least some keyless chucks, including those in Ryobis (your drill may actually be one) have a ridge in each jaw to grip bits better, but I know people who still experience slippage problems with them. As others have suggested, buy hex-shaft drill bits. But even the cheapest keyed chuck will grip better than your keyless chuck. |

They can break anything if you're not watching but the law won't allow us to keep them in a cage on the job. [8~{} Uncle Monster |
