Changing a drill chuck is not something that you do as a routine or something you will have to do that often but this does not mean that you should completely have no idea about it because some incidences will call for it. Before we go any further, you need to know that a drill chuck is what gives you permission to fix the drill bit or have access to inner parts of the drill. When a drill has not been in use for a very long time, it is likely that you will find the chuck rusted or when the drill has been used for so many functions it might crack or break. Either way you will need to change that chuck so you will need the ideas that I am about to give you.

  • Find out the chuck type that your drill has: not all drills are made with the same chuck type so you will have to first find out what which drill type your drill has. Most drills have a threaded chuck though you will a few others with a taper fit chuck. From the manual you will be able to find out which type of chuck so after knowing the chuck type you can go ahead and change the chuck according to which type it is.
  • Take the screw out: there is a screw inside the chuck and to remove it you will need to insert a screw driver inside and twist it clockwise since this is a reverse threaded screw.
  • Removing the chuck is not that difficult, here we shall look at how can remove a threaded on drill chuck and a taper fit chuck.
  • Removing a threaded on chuck
  • Keep in mind that chuck screws should be turned clockwise reason being they are reversely threaded to ensure that when the drill rotates the chuck does not get disconnected.
  • Grab an Allen key:because chucks are tightly fitted on it is usually not that easy to remove it which will require you to have a really strong tool like an Allen key to be able to take it off. Find 1/2 or 3/8 inch 90 degree Allen key it will help you remove the drill chuck effortlessly.
  • Place the Allen key correctly: the shorter end of the Allen key should be placed inside the chuck while the longer end should be left hanging down.
  • If your drill has high and low settings it will be best if you turn to the low settings first.
  • In case the drill has a clutch, the drill direction indicator should be in the position for drilling facing forward and also put the drill clutch to highest setting.
  • Properly secure the drill on a table: hold the drill firmly and turn the drill to about 45 degree, in this position it will be easy for the chuck to spin off once you hit it with a hammer.
  • Remove the chuck with a hammer: take a hammer and with its flat side hit the Allen key to make it spin clockwise, if it does not spin the first time, hit it the second time so that it spins and can be able to come off.
  • Removing a tapered fit chuck
  • Removing this type of chuck is actually easier than removing a threaded on chuck though you must have the right to tool to do it. There is a special tool for chuck removal and you should position it around the chuck from behind. You will have to hammer the tool until the chuck spins.
  • See what the problem with the old chuck is: check the chuck well to find out why it needs to be replaced or changed, if you find that the chuck is rusted or damaged. Any of those two cases will indicate the chuck needs to be changed.
  • Remove the chuck from the spindle: if your drill has a threaded chuck just skip this step since threaded on chucks come off the spindle immediately however if your drill has a tapered drill chuck it in most comes off with the spindle. Therefore to remove the spindle just hammer it out using a metal punch until the chuck comes off from the spindle.
  • Install the new chuck: check your drill’s manual or manufacturer’s website to find out the perfect size for your drill before you on to purchase one. Make sure the chuck you have prepared to replace is the same as the one you just removed. To replace another chuck just place the threads of the new chuck onto the spindle and twist the chuck clockwise endeavoring to make well tightened on to the spindle.
  • Insert the screw: in the beginning you will have removed a screw so begin by putting that screw back inside of the chuck. With a screw driver you should tighten the screw very well and your new chuck will be more than ready to start performing.


  • Drill come with different size chucks which means that you need to be very careful when buying a drill chuck to avoid making mistakes with the drill size. Check the manual before so that you are sure of which size is appropriate for your drill.
  • Remember that you always have to twist whatever tool you are using clockwise since drills are designed with reverse threading and screwing. Turning anti-clockwise like it is with other screws makes the chuck tighter instead of loosening it.
  • Have your materials ready before you begin, it makes the whole process faster when you have all materials handy exactly at the moment you need them.
  • Endeavor to check how tight the screw of the chuck will be after using the drill several times, with the new chuck it is likely that the screw inserted in there will become somehow loose which is not safe for the you the user.

In conclusion, changing the chuck is not one of those daily maintenance things that you have to do to keep your drill drilling and driving well but changing the drill once in a while will definitely be good for the drill.
