How to Replace a Cordless Drill Chuck: A Step-By-Step Guide

How To Replace A Cordless Drill Chuck A Step-By-Step Guide

First things first, what exactly is a cordless drill chuck?

Drill chucks are a common tool used to hold the drill bit for any drilling operation. It can be used for hand drills, milling machines, and lathes.

This specialized piece of equipment is used to get radical symmetry while drilling. You can loosen and tighten the jaw of the keyless or cordless drill chucks without a chuck key, which makes it easier and quicker to use during drilling operations.

However, you might feel the need to change your cordless drill chuck after a while.

So, when should you replace it? If the chuck wobbles, it can become difficult to drive screws or drill straight holes correctly.

As with any other component, a chuck can also wear down over time. It’s prone to gathering dust or rust, both of which can cause the drill to seize up. Therefore, it becomes necessary to replace the cordless drill chuck with a new one if it develops a wobble or becomes warped in any way.

Can you replace a cordless drill chuck? Yes, but you need to make sure that you do it correctly. There are two main ways to change a cordless drill chuck at home. Here is a step-by-step guide on all the methods you can use.

Using an Allen Wrench to Change a Cordless Drill Chuck

Removing Chuck with allen wrench

The first method we’re going to discuss is changing a cordless drill chuck using a simple Allen wrench.

What you will need:

  • An Allen wrench (obviously)
  • A screwdriver
  • A mallet
  • Thread-Locking Fluid

1. Removing the Screw

The first thing you need to do is remove the screw at the center of the chuck. For this, you’ll have to widen the jaws until they’re completely loose.

Most cordless drill chucks have this screw on the base. The screw is responsible for fastening the base to the case of the drill. If you don’t find a screw anywhere on the drill, you can skip this step entirely.

Do make sure you have an appropriately sized screwdriver that you can use. To unscrew it, you have to turn it clockwise – remember, righty tighty, lefty loosey. Usually, drills have a reverse-threaded screw, but make sure that you check properly before attempting anything.

The screws are usually placed in the drill with some thread-locking fluid so that they don’t come loose. This means that you’ll have to exert some force to remove the screw. If it doesn’t come out with a screwdriver, you will have to follow the steps below.

2. Inserting the Allen Wrench

The next step is to insert the Allen wrench into the cordless drill chuck. Do make sure to get the largest Allen wrench that you can insert into the drill safely. You need to turn the wrench in order to tighten the chuck so that it’s firmly held in place.

3. Setting the Gearbox

Now, you have to set the gearbox to the lowest possible setting so that there isn’t a lot of resistance from the gears. If you don’t reduce the level of resistance from the gears, it can damage the drill chuck.

4. Tap with a Mallet

First, you need to position the cordless drill in such a way that it lies horizontally. It needs to hang over the workbench for this to work. Take a rubber or a wooden mallet and hit the wrench with a sharp strike.

Most of the cordless drill chucks have a standard type of thread, but it can be reversely threaded onto the spindle too. If you aren’t sure whether you have a reverse thread or standard drill chuck, you can read the manual or contact the manufacturer. To loosen the chuck from the cordless drill, you will need to strike the Allen wrench with the mallet in a counterclockwise direction.

You have to make sure that you’re careful when you use a mallet. If you use too much force or hit it at the wrong angle, it can cause the drill casing to crack or bend. You can start with a light force and increase the force if necessary. If you’re just trying to loosen a stuck screw, a gradual increase of force is important.

5. Removing the Chuck

Once the screw is removed, all you need to do now is remove the cordless drill chuck by hand. Removing the screw will ensure that the chuck is loosened enough from the casing of the drill. You will be able to easily unscrew it by hand in such a case.

6. Add Thread-Locking Fluid

One recommendation that experts make is to replace the thread-locking fluid in the drill. Once the chuck is replaced, you should dab a little bit of the fluid on the screw’s end. Spread it evenly across the end by rolling it on your finger.

However, if your drill chuck didn’t have a screw, this doesn’t mean you’re off the hook. You will still need to use the thread-locking fluid on any threads in the chuck. These threads are usually in the area where it is screwed onto the drill bit.

7. Replacing the Chuck

To mount the chuck onto the cordless drill, you can use the same tools that you have above. Whether you want to clean and replace the original chuck or install a completely new one, this is how you do it.

The first thing you need to do is carefully thread the chuck’s base onto the drill’s spindle. The next step is to open the chuck up and insert the Allen wrench. Tighten the jaws of the chuck by hand. After setting it in place, you should insert the screw into place. Tighten it by turning it in a clockwise direction.

Using an Impact Wrench to Change a Cordless Drill Chuck

This method is usually used when the first one has failed to loosen the chuck from its place. Remember, try the first method before trying this one. The impact wrench is known to provide more force, which can tear the wrench away.

What you will need:

  • An impact wrench
  • A hex socket

1. Insert a Hex Socket into the Chuck

The first step for this method is to insert the hex socket into the chuck at the center. Carefully tighten the chuck to hold the socket into place. Follow the directions above to remove any screws from the chuck.

It is important to try the first method before this one because this method has a higher risk of damaging your drill or your chuck.

2. Set It Out of Gear

While the other method asked to set the drill at the lowest, for this one, you need to set it out of gear completely. It needs to be in a locked position so that it doesn’t move forward or backward at any point during the chuck removal. If it is not locked, it can increase the risk of damage.

3. Spin the Hex Socket

The next step is to carefully spin the hex sock in the reverse direction with an impact wrench. You need to use the impact wrench in small bursts until the chuck begins to loosen. Do make sure to use short bursts. If you’re not careful during this step, the drill could get damaged.

4. Unscrew the Chuck by Hand

After it has been loosened, you will be able to remove the cordless drill chuck by hand.

Cordless drill chucks are one of the best tools in the market for drilling operations.

They reduce the need for a chuck key while opening or closing the chuck’s jaws, which can decrease time costs.

All you need to do is to simply tighten the chuck after putting it on a cutting tool or drill by hand. It is perfect for machinists and workers who tend to lose track of their drill chuck keys.

It can also prevent damage to the teeth of the keyed chuck since they tend to chip or break due to the process of keying the chuck.

Do make sure to take care that you aren’t using a faulty or warped drill chuck for any operation. It will result in a mess of project since you won’t be able to drill straight holes.
