Why your drill chuck won’t tighten?
The reason your drill chuck won’t tighten is because the screw in your chuck is loose or you’re using the chuck incorrectly. Dirt in the drill or a rusty screw is another reason your drill chuck won’t tighten.
The drill chuck has clamping jaws that secure the drill bit. A screw inside the chuck secures it to the drive shaft. Because the screw has reserve threads and sometimes the screw is loose, tightening your chuck drill becomes challenging. If the screw in the chuck of the drill loosens, it can prevent the chuck from being tightened, which in turn prevents the teeth from moving.
To fix this issue, put the right screwdriver into the drill chuck and tighten it. Note that the thread on this screw is reverse, so you must turn it counterclockwise to tighten it.
If you’re new to using a drill, you might not know how a drill chuck works. If you don’t understand how to use it, you might keep using the drill incorrectly, which will make the chuck stuck and won’t tighten. If you forcefully open it, the screw securing the drill chuck can loosen.
There are two parts to the drill chuck. When you are adjusting or taking out the drill chuck, you hold on to the black part. The drill chuck is opened and closed by turning the yellow part.
Dirt in the drill
When you use your drill often, it will get dirty. Sap, water, and other sticky things can cause the screw in the drill chuck to rust. Water, in particular, can make it rust and get sticky. Because of this, it’s hard to tighten the drill chuck.
If the screw securing your drill chuck is rusted, your drill chuck won’t tighten. This can lead to damaging your chuck. The screws are one of the first things you should look at on your chuck. Even a small amount of rust can make them impossible to tighten.

- Put the gearbox in its lowest position.
- Place the drill so that the Allen wrench is on its side and hangs over the edge of your workbench.

- Thread-locking fluid should be applied to the end of the screw before installing the new chuck.
