Loose screw

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.


Incorrect usage

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.


Rusty screw

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.

  1. Get the right screwdriver at hand.
  2. The type of screw in the drill chuck will determine the screwdriver you use.
  3. Insert the screw by inserting the screwdriver through the hole made by the drill.
  4. Then tighten the screw in a counterclockwise position


Replace the chuck

Over time, a drill chuck might wear out, or it can accumulate rust or dust that will eventually cause it to loosen up. It is necessary to replace it when this happens. Here is how to replace it;

  1. Remove the screw from the chuck’s center. (If your model doesn’t have a screw, you can skip this step.)
  2. Pick the biggest Allen wrench that will fit.
  3. Turn the Allen wrench to tighten the chuck so that it stays in place.
  4. Put the gearbox in its lowest position.
  5. Place the drill so that the Allen wrench is on its side and hangs over the edge of your workbench.
  6. Use a mallet to hit the Allen wrench.
  7. Most drill chucks have a standard thread, so striking the Allen wrench in a counterclockwise direction should loosen the chuck from the drill.
  8. Once you’ve loosened the chuck from the drill’s body, you can unscrew it by hand.
  9. Thread-locking fluid should be applied to the end of the screw before installing the new chuck.
  10. Insert the new chuck in place.


Apply spray

  3. Close and open the chuck five times to spread the lubricant evenly.
  4. Use a soft cloth to clean up the extra oil.
