When drill bits come loose or keep slipping, it is almost always because there is an issue with the drill chuck. Worn-out chucks are the most common reason for bits to come loose but chucks that haven’t been cleaned in a while and chucks that are not fastened to your drill correctly can also result in bits that won’t stay secure in your drill.
To help you figure out what is causing your drill bits to be too loose to work, we’ve put together a guide that gives you more insight into each reason.
Why Drill Bits Come Loose
Some of the main reasons that your drill bits keep coming loose include the following:
The chuck needs to be replaced
The most likely reason that your bits are not staying put is a chuck that needs to be replaced. If you have an older drill or you have been using the same chucks for a long time, it is important to look out for signs of wear and tear. Loose bits are a major indication that it’s time to replace your chucks. Cheap chucks will mean even more risk of loose bits so choosing quality chucks is an investment. When choosing new chucks, always make sure that you choose the right type for your specific drill and project. Keyless chucks are ideal for everyday use. They loosen or tighten tools manually or by using torque. Keyed chucks use a key, and are typically best for heavy-duty projects that have a higher risk of slips.
The chuck needs a good clean
If your chuck is fairly new, another reason that bits won’t stay secure in the chuck is that it needs a good clean. Over time, dust, wood chips and other debris build up in the chuck. If you are not cleaning your chuck as well as your bits and drill, the chuck will have a higher risk of getting clogged up. This will make it harder for bits to be secured. If this happens, there are a few ways to clean the chuck. Compressed air will do the job quickly. Otherwise, you can also carefully open the jaws of the chuck and use a microfiber cloth to gently clean inside the chuck. Do this regularly to prevent problems from happening again in the future.
The chuck isn’t fastened properly
Another reason for loose bits is a chuck that isn’t fastened to the drill properly. This is more common than you may think, especially for those who are still getting used to their drill. When attaching the chuck to most drills, you should hear a clicking noise as it clicks into place. Depending on the chuck you are using, you may need to keep turning in one direction until you hear a few clicks or turn it in the other direction until you hear a single click. If you have not attached the chuck properly and you start drilling, your bit will keep slipping. This can damage the bits and even the tool.
